I might let it go if he just yells, but if I have to reach out and physically stop a collision because he isn't watching where he's going, I'm not going to let him push me while he yells. He has to keep control of himself.
As for the "people didn't pay to watch the officials" garbage, I don't buy it. I'm not officiating for the fans, either. If I want to worry about what the fans are paying for, I'll try out for the NBA. Just officiate the game and address the behavior. They didn't pay to watch me rcall traveling, either, but I'm still going to do it if necessary.

And the "would it make the game better" question is a great tool for borderline behavior that gets overused. Technical fouls generally make the game better, but they don't have to in order to be good Ts.
