I like to think of myself as a good tipper (Don't we all? lol). I'll tip 20% almost as a standard. I just can't bring myself to tip on takeout. I know people who do, and I see the space for it on the receipt, but if I'm picking up my Chinese/Thai/Pizza/Whatever, I don't see why a tip is necessary. It seems to go against everything I've ever known about the reason why we tip. How about you guys?
