Dan once brought pizza into his class and charged the students 25 cents per bite. What was the effect? Huge bites. His students, trying to avoid the pain of paying, thought they found a workaround by taking extra-large bites.

When the server drops off the check at the end of a meal, every one puts down their credit card. The server picks one, and that one person pays the entire bill. A similar, less luck-reliant version of the same thing is to have payment rotate among friends.
