Similar setup, this was Italian.. but yeah they used to get rooms busted by cops all the time. They had trucks full of slots. No one even sat in those places, they just went to pick up the cash every day (I know this because I accompanied someone on their rounds to pick up cash from the slot machine apartments once, and was kinda shocked that some of them had no one inside at all. Just like, some studio apartment on 14th and another on Canal and another on Ave B. Wall to wall with slightly used slots hah)

[edit] There was also one night I showed up to work only a few hours after the cops had raided the poker room, and they were just getting back up and running.
