When I was a kid, I'd go to the local K-mart(closed now) and buy ammo. The guy that worked the sporting goods desk didn't care that we were 12, or 14, 15, or whatever we happened to be at the time. He's make a joke about seeing our ID just to make us panic, then he'd laugh it off and ring us up. About 3 year ago, the same guy won the Powerball Lottery and took home about 60 mil.* Just goes to show you that good things come to those who do good things.
