I’ll be 28 in about a month. The guy looked at my ID and looked at me and said I didn’t look over 16. 
I know…no big deal, but I’ve felt wicked old and tired this week, what with being sick and all. teehee…it made me happy. 
I ordered a beer in a Ruby Tuesday’s and got carded when I was 39! (I never get tired of that story)
Don’t feel bad, I volunteered to help a fellow teacher out one time when I was 25 with her computer techology class at the high school vocational school. I had to check in with the office to get my “visitor” tag for security reasons. They thought I was a student, took the teacher coming down there (after trying to convince them for ten minutes) to verify I was not a student and actually an assistant for the day, LOL!
My husband (27 years old) has a very young looking face. A couple years ago, he had bought a few of those scratch-off lottery tickets. On one of them, he won about 50 bucks. He went to the store to cash it and they carded him (I believe the legal age for lottery tickets in Illinois is 18–correct me if I’m wrong.) The thing is that he was actually pissed about it! I would have been so flattered.
Last year, he cut his hair really short (it had always been really long), and the haircut really made him look younger. We went to a movie that weekend, and he got carded to get into the rated R movie we were seeing! They didn’t even think he looked 17!
And it’s been at least a year since I’ve been carded for anything 
Once when I was cashiering at a Piggly Wiggly in
South Carolina, I carded a beer purchase by a short,
thin, young-looking woman. Looked no older than 15,
but by her ID (and subsequently her birth certificate
because we just couldn’t believe the age), she was
57 years old.
Mind you, I’ve been asked by the register to card for
toilet paper, before. On a whim, I did it. Figured it
might ease the tension in the line. Made the customers
in line laugh, thankfully. The card even got noticed on
my journal tape later on. 
I was once in a bar with my mother, who got carded. I was old enough, but not drinking alcohol at the time.
She liked it. 
I think when people ask for a driver’s license they are checking for an address & other info so they can try to meet the person later.
I’m probably 20 years older than Montfort & even I got carded two months ago.
