Today we were playing the first round of local playoffs. My court had lost and my partner and I were watching the 3rd dubs play next to us. Our team was ahead on this court and one of the players on the other team was struggling, in particular with the serve return. One of this player's friends, not on the team, yells to the player ... curtis you gotta move your feet ... happy feet curtis, happy feet. Well, after the next point was over, I said to the guy quietly ... "dude, that is coaching and you cant do that". He flips out ... curses, calls me an *** and that he should be allowed to coach since he is not on the team. The guy left in a huff ..... Well, the rule is he cannot coach, and we were instructed prior to the match this was not allowed ... however would you have said anything, or just let it go?
