I remember back in the 50's and 60's when I was in school ( a loooong time ago!) the lunches were almost all cooked with real food ( except Bologna and hot dogs) . The only snack available was a vending machine that dispensed apples. A few years later , around 1969 or 70 they started selling cookies and and peanut butter filled crackers. That was the beginning of a downhill slide. Originally we didn't have soda vending machines either.
