Funny story...somewhat relevant. I was playing a guy 5 ahead 9-ball for $400. We both play pretty sporty, each stringing three racks a couple times during the set. When either of us would get an easy 9, or even an easy last two, we would hop up and rack the balls. We always EXPECT to shoot the ball unless told not to. One time he left himself a long straight in 9 ball. He shot it and missed. He was fine with it, but his buddy, a little trash-talking A-Hole who can't play at all, got pissed off at me for not conceding the game. This little guy wanted to start a fight with me. I asked the owner of the pool room (the guy I was playing) to have the guy leave, and he did. From now on I will only play the guy if his buddy isn't allowed in the pool room
