He always brings in an "Expert" to teach the bartenders how to mix drinks and another "Expert" to overhaul the menu and the kitchen, not once has he brought in an "Expert" to upgrade the pool areas of these bars, they have had some new felt installed on a few of the shows I’ve seen, but he could at least bring in someone from the local APA or Tavern leagues to consult with about table placement, lighting, equipment and the possibility of starting some league nights, or at the least the owner of the billiards supply company that services that area.
John Taffer is an expert in the Bar business, and that is a simple thing. Making money with Booze Sales. That is the Bar business, and if pool tables, music machines, food, or a DJ are in the Bar it is to keep customer there longer, buying more drinks.
I had a friend who owned several Bars with Pool Tables in Phoenix Area, he said many times Booze Paid the Bills. He did not want "A" Type Great Pool Players in the Bar, as they did not drink. He catered to drinker, recreational league players, and bangers who drank.
The guy who had the Pool Bar in Denver had some Bar Flies in his place at the start of he show. you know they Drunks who are there for the cheap drinks, and will drinks, and bum free drinks all day.
At the Show End, and 6 weeks later the Bar was making money on Booze, Food, and Renting Pool Tables, so Taffer accomplished his mission.
BTW IMHO it is today difficult for a Pool Room to make money, and maybe that is why so many have closed. An APA Operator is only going to take money out of the Bar Owner Pockets. If an owner was smart he would start some type of his own in house league, with a end of season CASH Payout to get the money for himself. IMHO.
