Good one!
You are not far from the truth though. Whadaya do when the break is over, it's time for class, and you have 8 games up on the machine from your original quarter? You can't just throw them away.
Answer: You skip class - day after day after day. Pretty pathetic. And yes, I was paying out of my own pocket.
That couldn't have been very expensive. If you were so good at pinball, it would only cost a couple bucks a day.
