I kinda see both sides. For George, he deserves respect to do his job.
Ultimately if I had to choose aside, I think it's a bit overkill to eject the PA intern.
They aren't part of the game, they aren't inciting violence- in fact, it probably adds some comic relief and gives an outlet for folks to laugh about the situation.
Players, fans, and others do need to show respect for the umpire. I get that.
But honestly, umpires have issues too and it's rarely spoken about.
Remember the Brett Lawrie incident? See, that was the ump's doing. He got mad because on an obvious ball 4, the enitre world didn't hold its collective breath to hear him say what we all knew. Lawrie trots down to first before he could render his verdict, so he called it a strike. That's cheating. It's cheating like a spitball is cheating, it's cheating like pine tar use, it's cheating.
Then here comes another ball four, five feet off the plate, and he calls it a strike. All because Brett Lawrie can't think for himself. So the umpire cheats again. All so his little feelings aren't hurt, he gives an out that should not be rewarded.
Brett Lawrie shouldn't show the umpire up, right? But- how many times do you see an umpire give a very exaggerated called third strike call. Like, he's almost happy to do it. Is that not showing the batter up? Bang bang plays at first are the same. It's like watching a theater production.
OR, could umpires may be human and can't help but raise their emotions on certain plays, maybe like Brett Lawrie can't help walking down to first on an obvious ball four?
Nobody is there to watch the umpire, if we could replace them with machines we all would, so for me, they need to check the ego at the door, do your best to get the call right and not worry so much about what everybody else thinks.
