Pizza token

I created these pizza tokens for my birthday! I wanted to invite my friends to a pizza slice and I needed a way to count how many they ordered. Basically this is what I did:Briefly talked to the store attendant (they were nice 😁) and explained the idea.Gave each of my friends a token.They “payed” for their slices using them.And in the end I payed the store based on the amount of tokens they had collected.Of course I could have just said: “hey, I want ‘x’ pizza slices", but where's the fun in that??
