sounds like someone has an inferiority complex
I look at this in another way, I am not going over there to undermind anyone, I am going over there to remind them there is a time limit, and we need to start playing again. Sometimes people get started in a discussion, coach might even be civil but asking too many questions for that place and time, the what ifs etc. and an umpire can get sucked into trying to explain things and lose track of time. There are also umpires who like to stand there toe to toe and argue that coach back into their dugout no matter how long it takes (sounds like this ump fit into this catagory) and there is no time for that in any game, let alone one with a time limit. It is not fair to the players to have their playing time taken away from them. You are a team out there and nothing like working like one, keeping your partner on track to get this game moving.
