I've got to be honest. For much of my life I had no concept of food costs. I think that's true for a lot of kids who don't have to pay for food. I'd eat the entire package of pizza rolls, not once thinking about the fact that they were supposed to last a week. The ignorance of a child makes it seem as though another bag of pizza rolls would just magically appear. In a way it did. It magically appeared because my parents bought a new one.
This kid got an early lesson in economics. You have to pay to play. That might be a little annoying when you're a kid and don't have much going on in terms of money, but something tells me that this kid was probably eating boat loads of cereal and needed to be stopped.
