True story that happened to me. An manager had several pages that he wanted to fax. Just as he got started, the secretary ran up to him, and told him to wait a minute, while she checked to see if there was enough paper in the fax machine to handle all the pages he wanted to fax OUT. He just looked at her strangely, and let her add more paper. I had this visual in my head of pages of paper floating thru the air to their destination.
I did gently correct her after he left.
