That really is too bad. You can use it by telling your son in a similar situation to calmly insist that she examine the ball mark.
I hate to think we're raising another generation of John MacEnroes, but it sounds that way if arguing and temper tantrums are the accepted way to win matches.
Another suggestion would be to summon the tournament official when you first see a court monitor isn't up to the job. It's too late when they spoil the match.
