I'm know I'm coming in at the tail end of this thread, but I have to agree with some of the points Teacherman has made. First and foremost, in my experience, most poolplayers are cheap people (see SI thread for further proof). Pool rooms don't make tons of money off the regular players who spend money only on table time and free coffee - they make money off the drinkers (at least, around here, they do). I managed a room for a while, and I found some of the things Teacherman has said to be very true - summer business is dictated by the weather, and so-called "B" players are the biggest complainers. As much as it pisses some players off, room owners HAVE to cater to the bangers, league players, and casual players since they are the ones who drive profit. Simple math and statistics prove this to be true. Although I frequent my homeroom often (I guess I'd have to classify myself as cheap, since I don't drink alcohol), a Saturday night couple will spend more on drinks, pool, food, and the jukebox than I will spend in an entire week. Those are the customers room owners need in order to survive. I don't think an owner should just ignore the complaints of so-called "B" players, but those complaints are often going to be outweighed by the almighty equalizer - MONEY.
Here's a fer-instance: my homeroom owner is switching back from Simonis 760 to 860. Most of the "players" in the room, myself included, love the 760 for its speed, and we recommended it to him to give it a try. However, the 760 is wearing out faster than the 860 did, which means the owner is going to have to spend money to have the tables covered more often. Rather than do that, he's going to switch back to the 860. We, the "players," are going to bitch and moan (I won't, since I understand the decision) about having to go back to the 860, while the owner is simply making a sound financial decision. He *tried* to cater to the players, but it just doesn't make any sense to spend extra money but not make any extra money. Bangers don't care about the cloth (since they call it felt no matter what it is anyway), and the cost is more than the owner is willing to spend, so I can't blame him. At least it'll still be 860, could be worse...
And, to get back on topic, ONE table at my homeroom has been shimmed (out of 16 GCs), and it is by far the most popular table for rent. People find out that it's tougher, and they all want to give it a shot. Sometimes that's upsetting, since it was shimmed for me.... But I digress. I don't think it really matters one way or the other if the tables are tight. I wouldn't want to play on 3.5" pockets all the time, but if the tables are shimmed a half inch or so, I don't think anybody but good players would even notice. Bangers simply don't care - they're not educated enough about the game to know what they're looking at. For a banger, ALL tables are tough, shimmed or not.
