Arrow - sitch

[mick]

PA Coach wanted another from the two games I watched.
(I'm still sittin' behind the timekeeper)

Timekeeper and Scorer have a little 3'-nuthtin, cute blonde arrow operator (6-7 yrs/-old) sitting between them.
No problems thus far.

Beginning the 4th quarter, the arrow is pointed to Red.
Red throws in the ball and immediately get ties up. (2 seconds? gone.)
White arrow on the held ball. White ball.
4 minutes later... "held ball".
Puzzled Ref goes to table and tells them the arrow is wrong because it was Red all at the quarter and there were no other held balls.
Table looks puzzled ???
Ball is given to White.
White wins in OT by three.

How do we prevent this?

Yes, the ref was politely jumped after the game. Not for missing travels, not for questioning the arrow twice, but for a game that ran 36 minutes.
