Being in the Florida panhandle, this is a huge issue for us. A lot of the bars in our league are run by non-poolplayers, and have no idea that you can't leave the door open or the tables will play like crap.
I agree that you shouldn't let yourself get too worked-up....it's APA, and designed to be fun. The rules are designed to favor weaker players (slop/take what you make on the break/loose rules on the double-hit). I've only made a scene one time over the double hit and that's because another 7 was giving a time out to a 2 and was instructing her to do a flagrant double-hit. Other than that, even if it's a 5 or a 6 I don't even bother....not worth it.
Well I disagree with the notion it's designed to be fun. Playing for fun is winning trophies .. There giving away trips to Vegas. That's gonna bring out the ego and asshole in people lol
