When I was a kid, the schools that I went to had hot lunch programs. They started out at a quarter and eventually went up to thirty five cents or maybe a little more by the time I was in junior high. I never got the hot lunch. It cost too much. I just brought a sandwich, an apple and maybe a couple of cookies in a paper bag. When I was done I'd fold the bag up and put it in my back pocket for the next day.
I always got a carton of milk. You'd bring a quarter to school on Monday morning and get a carton of milk at lunch each day of the week. Nobody ever checked whether or not you had paid, you just took the carton of milk from the box as you filed into the cafeteria.
I realize I could have just taken the milk and never given them my quarter on Monday. Never even occurred to me at the time and a quarter was big money.
