As a player 45yrs old now, and a paying customer of such places over 28yrs...
Bars sell cheap swill beer, cheeze doodles, and booze, pool tables are for customers to have fun with between buying drinks. Amongst pinball/video/darts/shuffleboard diversions. Whatever it takes to keep em happy suckers buying booze, the main moneymaking action.
"players" mostly drink water spend only for table time (until finished playing). Players rooms have good equipment at the outset ($$$outlay for the biz folks), some action and buzz, tournaments, promotion with the better players in town in the beginning, league promotion, the sales hook to get regulars... getting my drift? Rarely lasts, often no long-term follow-through.
Some monopoly rooms (Hawaian Brian's, Honolulu; Champions, Arlington VA) have a lock on the market, charge what they want and have a $nice$ bar, tasty/unhealthy chicken wings/fries and more delicious with alcohol deepfried cheeses/niblets (selling early cholesterol death, but we pool folks are 20, slim, young, handsome, and will live forever, right?) tables, some league nights, maybe music, and absolutely nobody leaves without paying $25 or more. Pretty soon owners figure out players may be where their heart is supposed to be, but the fat wallet of success doesn't logically follow.

Soon financial sensibility/responsibility and ladies nights, loud jukeboxes, poker nights, free pool after 12pm, and $2 drink specials make more sense for bringing in lots of warm bodies with cash than players alone (c.f. C.J. Wiley). And I can't fault these businesspeople for rational choices, in fact I am happy they keep the pool tables and don't give up space to competitive dance twister, rolller skating, or C&W Bingo games entirely. Please keep the stripped wet t-shirts _off_ the 3-cushion tables, the humidity and injustice of it all is a bitch if you fall 2mm short after a 35 foot 7 or 8 rail back-up shot out of the corner.
I also think any pool room is foolish not to offer gratis or almost free Saturday/Sunday early afternoon classes to beginners from scout troops to disadvantaged youths to church groups to league players, just to develop the market for future players, goodwill, and lust for better clean competition buried deep within the human soul. But I digress, and am perhaps looking for a clean future job. ennyway.
