Flamin' Hot Cheetos have long been the favored spicy snack in many elementary schools. At the school where I taught, the cafeteria sold small bags of them, and several students would sneak the Hot Cheetos out and snack on them in the halls between classes.
I didn't mind. Chris G. would rarely write his name on his papers, but I could always identify his work by the red-orange fingerprints smudged on it.
Then one day, in an enterprising bid to increase revenue, the cafeteria began to sell larger, 99¢ bags of Flamin' Hot Cheetos. A dozen fourth-grade boys bought bags, and each of them consumed considerably more than one serving.
