Studying Z- while the R's actions may not be your cup of tea and I could probably live without the histrionics myself, by rule there is nothing wrong with the actions taken and obviously the TSAA supported it. Maybe he is too "basebally" inclined and it certainly wasn't wise to throw in "and you're gone next week too" as that is out of his jurisdiction but we all have moments in our career that looking back, wished we had said or did something different.
Much like the debated Louisiana incident a few weeks back, these incidents don't happen in a vacuum. In every stomach churning incident I've been a party too, and thank God none have risen to this level, once you have a moment to reflect you can figure on where something went awry and learn from it. The R here is obviously an experienced official but we can never stop learning unless you choose not to.
I say all that to say this: Never say Never. If you ever make it to that level, you will find yourself in situations where you may not exactly agree with what goes on but for the sake of your crew you may have to swallow it.
