Had a referee last night who may have a short temper.
1) Stick his finger in my player's face.
-It had not been 10 minutes into the game. My forward got called offside a few times and would say, "how?" or "no way!" Nothing demeaning or anything IMO.

2) Got in my keeper's face.
-It was a corner kick for the other team. They had my keeper marked. My keeper had him arm extended to make sure he had space to move. Wasn't physical with it, only extended for space. Ref decided that was physical/rough and went right up to my keeper to warn him.

It doesn't really make sense to me. I know we nitpick about a lot of things, but it takes a big man to get in players' faces.
