When I first started working ASA ball in 91, we had someone like that. In fact, I was working a a game where just about the same stuff happened - baiting people so he could kick them out and go home early in a Sunday morning mens league...when I was done, I went home (about 20 miles), changed and went up to the local park where a FP tourney was going on. Our assignor, who also happened to be New York UIC, was there...and somehow in those pre-cell phone days, the first question out of his mouth was : "What happened down there?"
We always said that Bernie knew all, but this was ridiculous! BTW, the ump in question never worked again....
