I will just quote the assignor in my area after a game a friend of my called last season
She was really angry cause her partner wasn't even trying. He didn't run, didn't even attempt to call the game properly. After the game she said
"I never want to officiate with him again" (note this had happened before when they called games)
"I know, but you should know. When you looked at the court today, there were one official looking good and proffesional. He is not that official" (He has been calling games probably, 10 years longer then she, maybe even more).
Talk to your assignor, let him know how you feel about this partner, and if this ever happens.
Get in, get done, get out
Then take care of things after the game has ended (offcourse try to talk to him during the game, but if he won't listen, don't force anything and start an argument)
