We had this old corner store we used to go to, to play. the guy only had one or two machines in the back. We would put quarters up to hold our place. The store was all jacked up too, I don't think he sold anything there. All I remember is an old store with wooden shelves with nothing on them. I think the owner was an old drunk, but he never bothered us. He made his money from the pinball machine I guess. One ball was a dime, and 3 balls was a quarter. Did you ever hear of popping the machine?
