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.)
