Some of you guys take this stuff waaaaay too seriously.
I set this crew up expressly because I knew some of these guys freak out for not being uniform. The guy at the far right is laughing really hard at the guys on the left, knowing they're uncomfortable. By the third inning, everyone was in black jackets, but my point was made. Lighten up, Francis. It's a game, usually played by kids, where 99.99% of the folks don't give a rat's @ss how we dress.
I promise you, only other umpires notice the plate guys is wearing a different colored shirt. In the above game, everyone came away with a good experience, and a lesson learned. Plus the food that night was exceptional.
