I don't want to go through the whole story but I moved 5-6 pieces of Master my opponent used back onto his table three times. The next time I put them on the light while he watched me do it. For the record he was/still is a really good player.
He came to the table and pretty aggressively confronted me about "where's my chalk?" He carried on for a bit with his chest puffed out. I told him I moved it to his table 3 times already and he watched me put it on the light. I said I was sick of having to move a piece of chalk after every shot so I could properly bridge, and I was sick of it being in my line of sight. I also said (hopefully quietly enough so no one heard) that he is a good enough player to not have to use chalk as a target and to mark tangent lines and routes with it.
I don't think he realized I knew what he was doing and was pretty much on tilt after that.
At that point I didn't know him and thought he was an ass, turns out he's a pretty good guy. I don't know if it's related at all but he uses a magnetic chalk holder now.
