Again, pool's problem isn't players. Millions play pool each year.
Most pool halls have plenty of people playing daily, the issue with pool halls is just the business model in general.
They rely on people who must concentrate on what they are doing, to preoccupy themselves with food or alcohol. Its just not a winning business model.
That would be the same as a go cart track relying on alcohol sales to make money. You can't sell a service which requires a ton of concentration, then rely on food an alcohol to pay your bills, the two just don't go together.
This is why bars which either feature live music and dance or dance music sell so much more alcohol......the activities don't require them to concentrate and stay coordinated.
Pool attracts people who love to concentrate and are miticulous. This type of crowd is also something else......cheap. Or at least cheap when they are playing pool. So, raising the table rates will just drive them away.
Pool, in general is a barely break even venture, unless you're one of the lucky few who can turn a profit.
Pool halls shutting down isn't from smaller crowds, as much as it is from a poor business model of relying on alcohol/food sales to make a profit whilst using a high coordination game to attract customers.
(before anyone chimes in with "i see drunk people at the pool hall all the time," that's not the majority of customers)
There are only two things that will make pool itself profitable. 1, raising the table fees. This is why golf courses can operate. Their green fees are much higher than what it costs to play pool.(for the most part) This won't work likely, as people will just stop playing as they are used to lower rates. Pool tends to attract the not so wealthy as well.......or 2, turn pool into a spectator sport. Plenty of people order food/beer while watching other sports, not playing them.(pool will never be a spectator sport in its current form unfortunately.)
I've said many times over, pool is its own worst enemy. Its just one of those games that requires too much coordination to preoccupy yourself with alcohol, but its not enjoyable enough to watch that people will pay for it.
I am like you i love pool halls with only pool tables, but i think location of pool hall dictates which business model works, some locations have people that just want booze and food, other jurisdiction does not allow booze. But why not, mix it and make the most out of it, i know players there booze bill is higher than there pool time!
If it does not have booze then they would be no restriction on age, and all of a sudden pool tables cloth becomes table cloth!!
