Heck I never ate a HS school lunch. Parents could not afford it. I ate bologna sandwiches mom made, and bought a carton of milk for a dime. In grade school we ate at our desk that which we brought from home with a nickle half pint of milk.
A carton of milk a dime....did you go to school in the 60s...lol!
I vaguely remember paying a dollar 50 for school lunch!
