Here's a quote:
"One day, by chance, I walked into Smart Parts Auto looking for a used door handle for my ’96 Corolla. What I found was an elaborate handmade cardboard arcade manned by a young boy who asked if I would like to play. I asked Caine how it worked and he told me that for $1 I could get two turns, or for $2 I could get a Fun Pass with 500 turns. I got the Fun Pass."
