We know that there's quite a history to it. Think of John McEnroe, think of Ilie Nastase, Jimmy Connors, Andre Agassi. These men all berated chair umpires, famously so. Commercials have been made. John McEnroe has done,' you can't be serious' and all the other tirades, top of John McEnroe lungs over the years and none of them received a game penalty, would he( umpire) have done that with a man ? History has said, no. He would not have done that with a man.
