No the truth of the matter is most poolroom customers suck when it comes to keeping up with house cues along with other things.
Now you are on the right track but that doesn't begin to cover it. Banging them on the table is only the warm up. Try javelin throwing, standing on them and rolling them with their feet like mini timberjack logs, stirring the trash in the trash can, poking holes through the dry wall, sword fighting, playing large drum sticks on bar stools, poking holes in upholstered chairs, breaking them over their knees and opponents backs, etc.
And while were at it, lets guess how many times the paper towel holders and the soap dispensers have been yanked off the bathroom wall, or how many different objects have been stuffed into the toilets.
Now you may think I run a crazy rough room, but mine is clean, calm and mild compared to most.
P.S. None of the previously mentioned customers were allowed back in my room after their escort out, however there are four replacements for every one barred.
