You've got more chance of making money by acting respectfully and not getting in peoples faces when they're having a bite to eat or drink.
Leaflet idea is great. Make people aware without mithering. Can't see a problem with that, but it's probably because the club can't guarantee that people like you won't go bothering their paying customers that they don't allow anything.
