I used to live in a kinda poor area. Lots of people on some sort of program. And that program had really restrictive rules about what you can and cannot buy. For example, you could buy Skippy peanut butter but not Skippy light peanut butter (whatever that is). It caused great confusion for the people who needed food, huge amounts of labor for the poor grocery person, and a long wait for the other shoppers in line - just so the government can save a few cents. Unbelievable.
