So in Minnesota there’s this cultural taboo about taking the last piece. If there’s a group and everyone orders pizza, typically one slice will not be eaten. At the office if someone brings donuts, the last donut will be left alone. Possibly cut in half. Then that half cut in half, but always leaving at least a little on the plate. The reason is it’s considered impolite because someone else might want it. To take the last piece is a desperate thing to do. There’s even an expression: “I wasn’t raised by wolves.” Anyway, here’s the best local facebook post going around right now.
