I find it dismaying that children are made to pay for lunch in a place they have no choice but to be all day, especially considering that the quality of most school cafeteria food is poor enough that adults would only eat it under duress.
We got (decent in hindsight) free lunch in elementary, but that was an expensive private school; in public high school there was a cafeteria that I think charged money, but I wouldn’t know since I always went off the grounds to get Chinese or pizza or something. $2 for a slice and a Coke and put your surplus into Xevious or Spy Hunter.
