My wife insists on tipping 20% even when we order take-out. She tipped 20% to the pizza place (N.Y. Pizza) the other day after we called in the order. I freaked out, but she says i'm wrong and that tipping 20% is the "proper thing to do" even when ordering out. When I get take out, I only tip a few bucks because the food is handled minimally, and nobody except the cooks spent much time on the dishes. What do ya'll think?
