Baseball madness

Had a very uncomfortable situation at the 12U baseball game today. During the game, kids were on base, the coach and a parent got into a yelling match. I've heard about them but never witnessed. After the parent started yelling instructions to the kids, it went something like this:
Coach: The coach is right here.
Mom: Then start doing your job.
Coach: I am, you can shut your mouth.
Mom: You're right coach.
Coach: You can be quiet or leave.

I thought it was over but:
Coach: I will tell them when I want them to do something, I'm the coach. You can leave.
Mom: My kid is out there, I'm not leaving.

Keep in mind they're about 30 yards from each other

Coach: You can leave
Mom: You can't..
Dad: Please don't do this.
Mom: I don't have to listen...
Mom: And this is free.

I was rolling the camcorder on this but when I listened to it at home, it wasn't as tense. You could hear them yelling but the mumbling in the crowd, especially the other parents, husband, etc. was not very audible.

At the post game coach talk, he handled it pretty well asking all parents to not shout instructions to the kids. They will get confused and not perform well at all. I totally agree with the coach but he should have left the bench and asked the mom to talk away from the others. Man it was tense and made DBBI look pretty bad. Where were the umpires? I though they could have stepped in also. Did I mention this was the first game of the year? Nice
