Who knows how much of this goes on done a little less blatantly.
I had experiences with Leah a few years ago. I actually thought he was playing badly playing too many hands with a big stack in a satellite. Apparently he thought I was a weak-tight donk and was taking bullying a little far. He busted me out of a satellite hitting a 3-outer after being pot committed to call my shove. Then he hands me my mostly empty drink glass and says "throw this away on your way out". I threw the drink on his chest and left. Then the next tournament, he wins a pot from me and makes a separate stack of all the chips he won from me. Seemed like an aggressive jerk. If I was a fish, then why try to chase me out of the games.
