So a few months ago I got in a small weekly $15 8 ball tournament. The opponent broke and the table was just absolute dog shit, clusters everywhere, such a mess... most of my balls had no pocket. So I get to the table and play a safe, bunt balls to favorable locations and leave him hero shots or stuff with built in scratches, kicks, shots where you can't get shape, etc. I never try to make a safe look obvious. After about 4-5 trips the the table I can finally run out. After I make 4 balls and am set up on my shot, down in position, ready to finish the pattern, paused at the CB ready to go for final back swing this guy loudly says "Don't you know how to draw a ball?"
In my head I was like WTF? So I stand up, give him a "who the hell is this guy" confused look. Like I make eye contact and pull my head back dumfounded like I can't believe what I just heard. I can't remember word for word but I laid it on thick like he must not understand the finer points of 8 ball.
"Well, 8 ball can sometimes be a strategic game, it's not about running balls, it's never a good idea to just shoot your balls off and paint yourself into a corner... I like to get my balls makeable before I start running them willy nilly. You saw how bad the balls were laid out... heck you took the stripes, you saw how bad solids were. I'm working on getting my balls in a better position. I'd rather fix my problems and let the other guy take low percentage shots I leave him until I'm ready to run out. Why would I draw the ball? I'm moving my balls around and leaving you fliers. This isn't 9 ball, 8 ball is a strategic game, sometimes it's like chess if you want to win." And on and on for about a minute. No raised voice just a deadpan monotone fast talking monologue.
He didn't say another word to me the rest of the set, which was good. Oh, and when I shot the 8 Ball I made sure to do a really nice floater draw that went a full table length off of 3 rails.
I'm normally not like that but when some nit hollers "Don't you know how to draw?" when you're set to take your final stroke it's best to address the issue then and there before shooting. Dude just pissed me off. I think my mile a minute spiel actually ended up sharking him. He maybe made 2 balls over the next 2 games.
For some reason he was a sore loser and didn't even shake my hand.

Pool is half skill and strategy and half people watching and psychological warfare. The psychological warfare is played on the table in a respectable manner. Apparently not getting any half ass reasonable shot for 5 turns can make some people's head hurt. It's even better if you can make it look like an accident or like it was something sloppy/bad roll etc. Sometimes it can be more fun pissing with someone, but only if they start it!
