Stuff happens, eh? Doesn't say much for you then if you'd work with a jerk like this. Not only would I send this guy home, but I would report him to the state association. If you're so willing to lower your standards, it's not what you'd call a good reflection on you as a professional.

I'll work a whole season alone rather than have a partner who doesn't have enough self-respect to show up in uniform. If that makes me an SOB, so be it. If you don't look like an umpire, nobody will think you are one.
