What would you do?

[Shades of Gray]

Junior high tournament this week in local school, I was there as a spectator. Boys game with host team vs. visitors. Visitors coach get slightly mouthy and is given a Tech. At this point the coach for the girls team goes down to the boys bench and gets involved, even calling a timeout a few minutes later. When the team comes over to the bench, she then yells at an extreme volume to one of their players "the next time #21 (home team) does that, he does not get up, you understand me!!" To the kids credit, I did not see any action that was out of line, but this comment was so off the wall, I was incredulous. I mentioned this to the home team coach after the game, but he did not seem concerned and I am sure will take no action. The question I have is what should a spectator do in this case?
