"Inning or so later, there was a banger at 1B that the BU called out from the "C". Of course, it was the same team and the coach went from talking about that play to the strike zone. The PU asked him three times to drop the subject and the coach wouldn't, so he was sent to the bus. (SteveM, he must have learned that from you )"
Some coaches just insist on not staying around to see the end.
Good for the ump for recognizing and handling.
