Last night me and my friends went to our local bowling alley for something they call "sloppy bowling". I thought it was a good idea that might work for a pool hall in some places as well. At the door they take 10 bucks from each person and give you a card redeemable for 5 beers and you get to bowl as many games as you want from 10-12. They have this promotion every Sunday, and in a place like Indiana where a lot of bars are closed on Sunday it draws in a huge crowd especially local college students. Maybe this idea wouldn't work in a pool context, but I thought I'd just throw it out there.
