One Bite
If you’ve ever worked in food service, you’ll be familiar with the customer who eats almost their whole meal before deciding they hate it and demanding another serving on the house.
One time, when I was working at an unnamed fast food chain, this dude left literally one bite of their burger and complained to my manager.
My manager remade it for him and then cut off a piece the same size and only gave the customer that piece. The kind of stuff I dream about doing.
