In high school a guy in our group picked up his ball instead of tapping it in. On the next tee box, we told we would let him putt it in with a 2 stroke penalty or he will be DQ'd if he tees off. He gets pissed and the rest of the round after every hole out he says, "Did you see that. Was it legal. Are you sure it went in?"
I was paired with a guy during a tournament who did the same thing. He had a 5-footer for par, missed it short and instead of putting it in, he lifts the ball up with his putter and proceeds to the next tee. Honestly, me and another guy in the group were a little dumbfounded since we haven't seen that in tournament play before and conferred with the fourth in our group on the next tee box. He told him he had to go back up to the green before we teed off and assess a penalty (can't remember if it was a 1 or 2 stroke penalty) or risk being DQ'd. The group behind was already walking towards the green when he reluctantly went back, placed his ball and putted. He told the group behind, "Sorry about that. These guys play country club rules." The rest of the round, we pretty much didn't talk to that guy. Even the guys behind us were shaking their heads at him.
I've never thrown a club either. The worst I've done was yell out a few choice words or slam my club on the ground.
A buddy I play with says the same thing at least once after a bad shot. "Grrr...I hate this game!!! When do we play again?"
