Replying to Kicked out of an AAU Game?

So my younger brother had an AAU basketball game, and during the game, one kid got a cheap foul, no big deal.  The kid then yells to his coach, "Coach I need to come out, I have four".  The ref gives him a technical for yelling at his coach.  Then the kids dad yells at the ref "Why did you give him a technical?"  The ref then proceeds to kick the father out of the gym.  The father politely walks out of the gym, but stands in the doorway.  The refs stop the game and make the father leave the premises completely.  They then proceed to tell the scorekeeper (who they didn't know was the wife of the father) that that man is never allowed in the gym again.


So I ask you Newschoolers, is the father allowed back in the gym to watch his son, who he pays money to allow him to play?
