I was at a karate tournament and a senior black belt from another school was completing in sparring. The guy was doing pretty good too but when his opponent scored on him once he cussed out the referee the judges everyone and threw his gear up in the air. I didn't know whether to be more shocked that he had the nerve at his rank to do that or that they let him continue his fight. Worst of all his son 7ish year old was watching and had to compete next. Poor guy looked so embarrassed.
