You go to a nice sit down restaurant, the waitress brings you over some water, fills your coffee, brings you a drink. Then brings out an appitizer. Refills your coffee, water etc. Takes your order. Brings out your food. Comes back, cleans off your plates. Brings out dessert. Brings out final check. Say your looking at 20 bucks. I'd tip easily 15 to 20%.
Other option, I order a pizza by phone. Person takes the call, person makes the pizza. Then they hand it off to you to deliver. Do you give them a cut of your tips? Doubtfull. If I order one pie you probably get a buck, if I order 2 i'd probably give you 2 bucks. If you want 15% come back after the game and clean up the mess, then i'll give you a fiver.
