My ex-stepfather required my brother and me to use it for all adults. I resented using it for relatives and friends and so gave it up when I hit my teenage years. As a matter of fact, I’ve called my grandmother by her first name since my late teens because we worked at the same place for several years. She likes it because it’s more familiar. I’ve asked all of my nieces and nephews to call me by my first name.
I still use it for strangers mainly because it’s expected 'round heah.
I was raised in Florida in a generations-old Florida family. Yes, ma’am and Yes, sir were non-negotiable when speaking to anyone older than you. If you were speaking directly to them, it was Mom or Aunt Jan or Granny or Miss Paulette, but if you were responding to a question or acknowledging a direction, it was Yes, ma’am or No ma’am. Still is, in my family. I don’t have kids, but if I did, that’s how I’d raise them.
It’s not bootlicking any more than “please” and “thank you” is bootlicking. It’s basic courtesy in many parts of the US, though it may not be common where you live.
I’m in the South, North Florida to be exact. It’s common, but not among family members.
I always did it to adults I didn’t know.
To adults I did, it was: Mr/Miss <first Name>.
At school we’d use “sir” for the lay teachers but in social situations we were taught to address people by their surnames: Mr X; Mrs Y. Sir/ma’am socially was considered rather odd.
Your home is your home. I say “Yes sir” to my dad (but never “Yes ma’am” to my stepmother), but other rules happily apply in other households.
I expect and demand that my daughter to address all adults as “Sir/Ma’am” - I have no fear of immediately correcting her when she flubs, much to her displeasure. 
However, she’s a fast learner.
I don’t expect her to say “Yes sir” to me, unless I’m lecturing her about something - It’s a situational thing, one where you just have to be there. 99% of the time it’s “Dad” or “Daddy”.
Preach on, brotha. I yes ma’am and yessir and no ma’am with the best of 'em. Oddly enough, I learned this as a kid, but it really became a habit in junior high, when most of my age bracket were dropping their manners like they were… well, going out of style. I, too, might have lost the habit, except that my 9th grade civics teacher was a cutsie-pie 26 year old at her first teaching job, and called us all Miss/Mr. firstname and occasionally Miss/Mr. lastname. She’d also “yes ma’am”, “no, sir” and “thank you, ma’am!” us as well, . It encouraged me that she, barely older than us, showed manners to be charming and endearing and respectful to people in all different stations with respect to yourself. That is to say, she treated us with manners and courtesy, even though she was “the boss” and we were a herd of 13 year old maniacs. And we loved her for the way she made us feel like… people. I’ll never forget how it feels being addressed personally and with courtesy, and it’s a habit that has solidly stuck.
I was raised to call people by their title (Mr., Mrs., Ms., Dr., Fr., Sra., and so on)+ last name. Now as an adult, I sort of wish I could still use this form of address, but it’s so uncommon in my age-group as to be laughable, so I don’t. It would be nice to have some way to address someone with whom you don’t really have a relationship–I feel awkward calling my neighbors Leroy and Nancy when I’ve seen them twice face-to-face in three years. However, I don’t know their last name and this is how they were introduced so here I am.
I was raised that people have names and to use them. I would never dream of calling my parents sir or ma’am. I think they’d check me for a fever. I never called adults other than teachers Mr or Mrs or what have you. I was on a first name basis with almost all of my professors in college. I find needless formalities demeaning (to both parties). When I was a TA, I couldn’t stand students that called me anything other than Sarah. I’d ask them to use my first name and they still wouldn’t and it drove me nuts. And that was in California!
I don’t think I’ve used Sir or Ma’am outside of dealing with customers at work ever. All people are equal, none of this more equal as a sign of respect thing.
My parents never had me call them ma’am or sir, but instilled in me the idea that pretty much everyone else in the world older than me was to be addressed in that way. Having been raised in Georgia, I thought this was a fairly common practice. My fiancee’s parents, however, not being from the South, looked at me like I was utterly insane the first time I met them and called them ma’am and sir. I’m still not at all comfortable calling them by their first names as they’ve requested.
If a gentleman holds a door for me, I say, “Thank you, sir.” I don’t care if he’s some scruffy-looking bum; I want my kids to learn manners. I’m trying to teach them to address women as Ma’am or Miss Firstname. They’re not talking much yet, so sometimes it’s “Miss P,” rather than Miss Patricia, for example. When they’re older, I’ll expect them to call the neighbors or other adults Mr. or Mrs. Lastname.
I find that people are nicer to me and my small herd of children if we’re polite. At the very least, it’s better than, “Thanks, dude.”
Kid #2 is just starting to talk a lot. I tried to teach him to say “hello” on the phone, instead of “hi." So he thought he had it, and ran downstairs to his teenaged sister, and said, “HO!” She was more than a little offended. 
Much as with other people in this thread – If I had children, I would want them to call adults they didn’t know “ma’am” or “sir” (or “madame” or “monsieur” as the case may be), but I’d want them to call their relatives by regular terms (Uncle Theo, Gramma Lynn).
Oh, I forgot to mention that while I think it’s polite and would be nice for my kids to say ma’am and sir to elders outside the family, ironically, I don’t particularly care if others say sir to me or not. Go figure.
I come from a Southern family, so I learned by example (as opposed to having it beat into me) that elders (especially outside of the family) were to be addressed as “ma’am” and “sir.” This is also how I learned that some close-to-the-family-but-not-quite-family elders were to be addressed as “Miss [firstname]” or “Mr. [firstname].”
I was never, ever required, though, to use “ma’am” or “sir” when addressing Mama or her siblings. I did use it, though (since everybody else in the family did) for my grandparents and for *their * siblings (great-aunts and great-uncles) and others of their generation. I still do.
Not only that, but I tend to use it (depending on the situation) for strangers who are closer to (or even part of) my generation, and those people (this is up North, where I live) are either pleasantly surprised (“Ohhhh, you must be/you’re definitely from the South”) or somewhat put-off (“That makes me feel OLD!”).
As for myself?
I couldn’t imagine that I’d ever require that someone address me as “sir,” but I gotta confess: I **totally ** dig it when it happens. Given that we, as *An Arky ** so aptly pointed out, are becoming a nation of slouchy, rude people, I think that something as simple as addressing someone as “sir” or “ma’am” (especially when a child or younger person does it) shows a touch of…what’s the word I’m looking for?..yeah, class.
*Not, mind you, that this is the *only * way for someone to demonstrate that they have class, as there are certainly lots of people who use “sir” and “ma’am” who don’t have any class. I still dig it, though.
Wow! What a way to make everyone hate those dinners. I always thought family dinners were a time to break bread with the people you love, and to catch up on the happenings in their day. But I guess she sees a family dinner as more of a boot camp session.
Ask her if she thinks putting their elbows on the table will matter when they come to visit her in the nursing home. Or don’t visit.
I remember the first time I heard a kid address his dad as “sir” (it was an American movie, and the father was a conservative “send the kid to military school” type), it seemed jarring and completely outside my experience.
“Mum” and “Dad” for parents. “Aunty and Uncle Firstname” for adult relatives and other adults known well to them."
“Madam” and “Sir” for adult strangers (“Ma’am” sounds a bit too British or American [depending on the pronunciation] for an Aussie kid to use without seeming stilted).
I’ve had uncles and aunts who have asked me, as an adult, to drop the “Uncle” or “Aunty” and just use their first name, and I must confess I’m never entirely comfortable doing so.
I grew up in the rural South, and it is common in these parts to hear children addressing adults as “sir” or “ma’am”. But my parents (both well-raised) never taught me to do that. I think they were concerned that regular use of such honorifics might lead to a habit of being deferential. Let’s face it: not everyone who’s older deserves automatic deference.
My feelings exactly. Raised in the south, I call everyone I don’t know ma’am and sir . Teaching my kids to do the same. What is wrong with being polite? And this is whats considered polite here. As is saying “pardon” saying “what” is considered rude. Things are different in different places, you just do what you know. I daily have people who are my grand parents age call me ma’ma so its not even an age thing. Its just how you get a strangers attention instead of “hey you” ! 
Well, if the children say “ma’am” or “sir” in a Southern or English accent (and aren’t from the South or from England) they would come off as being rather flippant.
I grew up addressing adults as Mr or Mrs.
My kids address adults either as Ms/mr/coach (first name) or by their last name.
When I am called Mrs. ( last name) I always say to the child, Mrs. (last name) is my Mother in Law. You may call me Ms. (real first name) or ( what I usually get) (my kids first names) mom.
I have probably exceeded the legal use of () in this post.
