Shut Up!!

[rainmaker]

A) I would never say "Shut up" to anyone during a game, unless it was someone with whom I had a relationship outside, such as a friend or family member and they were just teasing me. In the OP, that doesn't sound like the sitch, but at least the partner said it quietly so as not to humiliate the person. Even so, it seems risky.

B) The best way to handle the table is to remind the folks there before the game that they are now officials and may not comment on the calling of the game. If you say this before the game, then if there's any "opinion", you can remind the table person quickly, without having to explain.
