What happened when after asking him to modify his behaviour and moderate his language, and he failed to do so, they reported him to a steward?
I did ask the question about reporting this sort of thing to a steward. My friend was surprised that the crowd did not self police . Her party were more interested in the game, especially during the comeback and didn’t want to cause any more of a kerfuffle. They tried to ignore the idiot and could feel the embarrassment of the people around them.
