I was at McGlynn's in Glasgow last night with some friends. (Yes, not only did I leave the City, but it was a work night too!) After ordering a Yuengling (my beer of choice), the waitress for my ID. I just stared at her dumbfounded. I'm been carded twice in my life. (I've always looked for my age.) And once was because everyone I was with looked underage, and I was only 23 or so. She apologized and said she's carded older people to which the next friend to show her his ID said, "Yeah, like me."
I guess it's because McGlynn's is close to the University of Delaware, but it still stuns me.
