Coach walks off floor....with players

[NYBLUE]

Girls AAU Tournament played back in early April.
This particular game was 16 and under (I think).

Coach asks for a TO midway through the 1st half and wants to talk to my partner and I at midcourt. He proceeds to say he doesn't want to see any of his girls get hurt and asked if we can tighten up the game a bit (we had already called 8-10 PF's at this point). He didn't even talk to his girls during the TO, just us.

Early in the 2nd half, coach asks for another TO and immediately instructs his girls to pack up their stuff and vacate the bench. Nobody said a word to my partner and I nor to the other team and coaching staff.
Apparently, he wasn't getting his way and called it quits.
At the time of forfeit, his team was trailing by 12 or so.

Anyone ever see or hear of something similar happening?
A coach simply pulls his players off the floor and leaves??!!!
