In all reality if you are a good pool player and something distracts you, simply get up from your shot, rechalk your cue and look at it again. In pro tournaments I can see where they would ban all cell phones, pagers, etc... but when you are in a local pool hall, the cell phone going off isn't any different from someone walking by the table, the jukebox starting up, the intercom system coming on, people laughing and talking loud, etc. I agree that it is a crappy thing to do, but what can you do about it. Just get to the point where it makes you want to beat him more!!! Maybe eventually they will catch on and stop doing it!
