N and I are going to do a sushi eating contest. It's not volume because he is a bottomless pit and I am not completely bottomless. There is a local business here, Bushido, and they have a contest that if you can eat all 10 spiciness levels of their spicy tuna roll, you get a $50 gift card. The good news is that you can eat these rolls over any period of time, so we wont' both be shoveling sushi in and kicking ourselves later when all the rice expands and we burst open.
We both are confident that our selves can finish but doubt the other's ability. What should the wager be for our contest? We are both broke so monetary bets are out. He wont' clean up to my standards, so cleaning is out. What is there left for friends to bet?
