What does officer short shift from Dictionopolis mean?

"Officer Short Shift" is not a character or a term from the book "The Phantom Tollbooth" by Norton Juster. There are several characters within the book who could be considered "short-shifting" others, but there is no official character with that name.

Perhaps you are thinking of a different book or story?
