I think “no problem” sounds sort of crass. I say you’re welcome.
This made me LOL, and was also a more elegant way of phrasing my intended response. So, thank you.
Whistler?
I think “no problem” is perfectly appropriate for some situations, like if you take the time to do someone a favor. It assures them that you weren’t put out unduly, and that helping them has not caused you a hardship.
Now, if you are at work, and reply to a customer with “no problem”, it creates a bit of an awkward implication, in my mind. You’re now implying that you did them a favor by ringing up their Big Mac, when it’s just part of your normal job.
This isn’t a huge deal, certainly, but “my pleasure” or “you’re welcome” are more appropriate in that setting.
I’m not against “you’re welcome” per se, but I’ve gotten used to “thank you/thank you” such that “you’re welcome” sounds strange now. And the double thanks makes sense, even if only from a Stupid Management Perspective; the customer thanks the employee for helping them, and the employee thanks the customer for giving the company their business.
“No problem” has the same potential pitfall as “you’re welcome,” implying that helping the customer could have been a problem, but it never seems to be taken that way except by the overly pedantic. I’ve used “no problem” and variants on it for 10 years now, and not once has anyone commented on it. But then, I usually put enough helpful sincerity into it to choke a horse. 
I forgot one that I sometimes use: “my pleasure.” Although perhaps it belongs in the pretentious thread…
Let me expand on that. I say “No worries, mate, cobber, bluey, dingo, me old china, eh, reckon, Dave-o, Steve-o, John-o, everybody-o.”
That’s right, France.
See, I disagree with this. I think “you’re welcome” has more of an implication that you went out of your way to do the person a favour. I guess it’s just a matter of interpretation, but it seems to be shifting over time. Maybe part of the issue is the sarcastic use of “you’re welcome”, eg.:
Person 1: holds door open for person 2
Person 2: walks through door, says nothing
Person 1: :rolleyes: WELL YOU’RE WELCOME!:mad:
I say “you’re welcome” and like hearing it. I hate the American “uh-huh” in its stead.
To my ears ‘You’re Welcome’ never sounds patronizing as some have described it. I use it all the time. I find it fascinating that it can be perceived so differently.
Of course, I’m on the other side of 50 now so maybe it’s just my age showing. 
It’s not . Remain polite.
Same here. There are other responses that are acceptable but there’s nothing patronizing about “You’re quite welcome” It essentially is saying, “I was pleased to do it”
I, too, hate “uh huh”. It just seems terribly rude and kind of … grudging.
I have to clarify my post. For me to say “you’re welcome” seems too formal in my head like “you should be thanking me, I did you a favor”. If someone were to use “you’re welcome” in response to my “thank you” I wouldn’t think anything of it, except that they were polite.
It’s one of the many incongruities of my brain that’s at fault. Not the fault of anyone saying “you’re welcome”.
I blame John Hodgman.
It is kind of situational for me.
For day-to-day things like receiving a thank you from a clerk or waitress, I usually reply with a thank you.
For things like gifts or favors (I drove 45 minutes to help you with your broken down car) I always use the more formal “you are welcome.”
That’s what I always thought. Thank you.
I use “no problem” or “no worries” most of the time. Maybe because I don’t want to suggest that I was happy to do something, but it didn’t cause me any aggravation.
Or because I started doing it once and now can’t stop. Help me.
Yeah, apparently my parents were terrible influences as well.
I love meeting these type of people IRL though. Easy to get under their skin, and highly entertaining!
Your parents clearly raised you well.
