almost forgot
before I go
I have upheld a protest by the Twins in a game they lost to the Marlins, after all the calls went against the Twins, only to see the other team providing drinks to the ump--maybe they didn't, but it looked that way--sitting there, sitting with them, sipping away, after the game, like, in your face, Twins
so, I have upheld the protest

umps should always maintain the appearance of impartiality, and avoid hanging out with either team before or after a game
