Plate Conf WTH?

[MD Longhorn]

2nd game of 2. New partner I've never met with hokey mechanics but made decent calls in game 1. I'm dish and we have 45 minutes between games. We head to the umpire room, talk a minute, and he leaves at about 30 minutes before game time to go to the bathroom.

20 min before game time I'm wondering what happened to my partner, but I head to the field anyway after looking around a bit. I get to the field about 15 min before gametime ...

And there's my partner, with both coaches, at the plate. He'd already done the coin flip and was just wrapping up whatever speech he made as I make it to the plate - at which point he says, "Anything you want to add, partner?"

WTF!
