Don't recall coke machines until I entered high school. I do remember pizza though! And cartons of milk, milk so warm it was nearly curdled by the time I slurped it down.
Now to survive it’s dodge the Knockout game!
I remember eating school cafeteria pizza that was so greasy, that you could literally squeeze a pint of oil out of every slice. But you could always wash that down with those little half pint cartons of milk. I still wonder how I managed to survive the 70’s as a kid. BB guns, big wheels, and BMX bikes, that’s how we rolled.
