True story, I was in a target, when I was still young and dumb and blissfully unaware of how age ratings worked with cashiers at big box stores, and I tried to check out with a copy of Halo 1 on PC probably around 2005-2006. The cashier was like, uh, I don't think you're old enough to buy this, and without missing a beat this random guy behind me said "Yeah, I'm his uncle, he can buy that." I've always wanted to repay that favor to some random kid, but I don't know if I could in good conscious xD.
