I've been to several businesses that have pool tables in them, but only a handful of "pool halls". I will tell of a couple that I really enjoyed, one no longer in business unfortunately.
A 16 year old kid walks into a poolroom in St. Louis, grabs a rack of balls, a cream soda, and a couple pieces of chalk and walks through the old style counter things (not sure what they are called) that they use at amusement parks and such to keep track of the people that entered that day. You immediately run into a couple Billiard tables, a table that says "one pocket only" and then some 9 footers. A couple bar tables and a snooker table also. Then there are pictures all over the walls of all the events that happened in this place over the years, and you see pictures of Nick Varner, Louie Roberts, Tom Ferry and other local gamblers. The kid throws some balls on the table and practices for awhile and enjoy's his cream soda and then takes a break and watches some sports center. A black man has been watching him and says, "Hey kid, what are you playing over there?" The kid says, "nine ball." The black gentleman says, "I like one pocket, but I'll play you some cheap 9 ball so you don't have to play by yourself." Of course the young kid thinks he is unbeatable and really thinks he is about to make some more spending money. Eventually, the black man starts some small talk and realizes the kid is the son of somebody he knows and says, "I can't play you out of respect for your father, but I'd like to introduce myself, I'm Cliff Joyner." That was a good "pool hall" experience to me and that was at the Cue and Cushion in St. Louis, MO. There are plenty more stories of this genuine pool hall.
I'll save the other story if the thread stays alive.
