Very inappropriate comments from fans and how to address

[cardinalfan]

A few years ago, a small rural school. Older man in overalls on the front row tells me I need to "help my boy", speaking of one of my partners... a young black man.
At halftime, my partner asked me why I let him make a racial comment like that. I was a little embarrassed that I had taken it to mean he was young and inexperienced.
Dead ball in the second half. I'm in C, right in front of the old man. This time he says, "You should know better than to bring one of them with you".
Told the school administrator I wanted him gone.
He got a round of applause as he left... I got hammered the rest of the night... it was worth it.
