When do you stop ignoring fans?

I once had a 2-7 off suit and was betting like I had a pair of Kings. Someone called my bluff, too, just like this guy called the PU's bluff. The PU had no authority.

This is why I ignore the fans, because I have no authority over them. If there is an issue in the fan section that needs to be addressed, I let park/game management address it... after one of the other fans complains about the situation. It's not my problem. (Threatening a participant, coming on the field or throwing something onto the field is about the only reason think I would notify park management myself.)

You just brought to mind a situation that occurred at a rec-league game that we had to miss.

Visiting team has one or two loud and obnoxious fans. At least as bad as OP. I think what sparked the following was a close call at first.

PU, finally getting enough tells a fan to shut up or he'll throw him out. Visiting coach reportedly tells the fan "Don't worry, he can't do anything do you." [Really helpful, wasn't she ]. Anyway, the fan follows her advice and keeps haranging the ump, who then tells him he has to leave. Eventually fan leaves and game resumes.
