Once I saw a player in a tournament scratch then drop the cue ball to the table from about three feet in the air. He was playing one of the owners of the hall. I found this disturbing. If it had have been my table the guy would have woke up looking at the ceiling. Same tournament. Some players playing by the rules set forth. Some not. One player didn't seem to care for the magic rack or the four (IIRC) balls past mid table rule on the break. Used the standard rack and ignored the set forth rules on legal breaks. I was a spectator but it was kinda sad nobody called him on it. Especially since he was setting himself up with the racking of the balls. One bad apple.
