Last week had trouble with a coach, yesterday a parent!!! Yesterday I was reffing U11 league cup semi-final (Blue vs Red). I expected it to be a good game because blue had one their league and only lost once or twice all season. Red hadn't had a bad season either. Had two parents as linesman. I had reffed the blue team most of the season because in our county, from U14 and below, clubs are assigned refs to do as many of their home teams games as possible. Linesman from the away team (red) was arguing every decision I made in the first half. I tried to ignore it and at half time I acknowledged that I had not had a brilliant half but knew that I was OK and tried to change it for the next 30 mins. Also I thought about dismissing the linesman because he wasn't great and arguing after every decision but they asked to change so I gladly said yes!!! He watched the second half and argued about everything. With 15 mins to go I gave a foul for the Blue team, he shouted again and did the sarcastic cheer as if I hadn't given anything all game (I think there had been 10 fks and a pen by that point). I went over to him and said 'Be quiet or go away! You've argued after every decision and I have had enough! Be quiet or go!'. It's fair to say that I didn't here a single word from him for the rest of the game but could I have managed it better? Should he have gone? (there was no bad lang. from him). If it happens again what should I do next time?
