I had a ref use foul language to me after a match when I was asking him a question. I was not trying to be brash with my question, but he said, "I don't have to answer any of your questions, A-hole." I later found out that he was reffing games for schools that were competing in the same region that his son's team was in. When I told the AD, he called the coordinator, and he wasn't allowed to ref any games in our region.
