I work in a movie theater that has a liquor license. To all you suburbanites that have only ever been to one of the major chains, this is a strange concept, I know. The thing about liquor licenses in the proud Commonwealth of Virginia is that they're hard to acquire and even harder to get back once it's been revoked.
As such, my bosses are very protective of their ABC license, and the policy is that everyone coming in must show an ID. There are, of course, cases when we could let it slide now and then. 85-year old grandmothers, for instance, or if they're with a parent. But when it's someone who looks like they could be underage and doesn't have their ID, my policy is that they're not getting in at all. Even if someone's obviously of drinking age, I stress that they will not be consuming alcohol while they're here, and then tell their server that they can't get booze.
But what baffles me is that anyone would come to an establishment that serves alcohol without an ID. I try to give them a chance, by asking if they can run and get it, but they'll usually even harder to get in. My favorite is when they tell me "Um, I came from Maryland..."
Really? You crossed the state line without identification? Are you an idiot? Did you think I would break the state law to let you in? Or maybe you think I have access to some huge government database and all I need is your name and address? SURPRISE!! I have no such access and you're not special! Now go home, because you're not getting in here!
