One time I was going to pick up some beer with some friends, everyone was 21, the driver just waited in the car. We all purchased our booze and walked out, then the cashier comes running after us and says "excuse me but we can't sell to you" And I'm sitting there blank faced thinking why not so I said "we're all 21 we all showed you our ID's and you've already sold it to us what's the problem?" So she said that we were buying for someone underage because someone was sitting in the car (the driver was 21 with ID, he just wasn't getting anything so he didn't want to go in) so we argue for a few minutes and she says that she is going to call the police for distribution to a minor, so my friend gets out and gives her his ID, and she wouldn't relent, so finally I lost it and just go off on this woman I mean really let her have it and her manager is outside trying to calm us down while I explain this idiocy to him, and he sides with her! Every single person with us was 21 with ID and they were saying that they were going to call the police! Finally I got fed up told them exactly where they could go and we drove off, just ridiculous.
