Welcome to my Gold Coast story. You kind of ruined the punchline. If you filled up a punch card, you got a free dinner. I'd run my quarters through once, then put the coins into my trench coat pockets. After the first two days of the "slot club," I had 20-some free dinners. I was actually staying there, so I would go up to my room and dump the coins out of my coat pockets, then go back downstairs and rinse/repeat, as you suggested.
Ah, those were the days.
