Hey, do you mind if I make a suggestion? How about a casino? It could be part of the club or a separate building. You could bet your body on it, that kind of thing.
I have something planned but the casino can only be accessible from later in the story
-Melo: Hey casino, I'm betting all my money/myself
-casino: Okay, if you lose you become someone's toy or something like that.
