A pool hall isn't a charity, it's a place of business.
They don't need my support, they need to work hard for my business (and my money), and work harder at keeping it.
If a pool hall goes out of business it's not the fault of the patrons, that responsibility lies on the shoulders of the owners.
If a pool hall is over charging for food and items, and the customers are to wise to pay for it, then it's the pool halls fault, not the customer.
This isn't the movies, a band of friends aren't going to form to save Average Joes Gym (oh shut up, you loved that movie).
I run my own business, how would it sound if I were to blame my customers for going off to a different designer that did just as good work and charged half the price? But they don't, because they know I offer a fair price for work that is well worth it.
I guess I must be lucky to be in this area, most of the pool halls down here charge a price that the customer is happily willing to pay, and in most cases if you're a regular the owner(s) will usually help you out.
