I have a funny story along these lines. A co worker had worked at a big engineering company in Houston back in the '70s. They had this hippy dude, that did word processing that no one else knew how to do. People put their work on his desk, and soon he had it done.
One day, he was in the elevator, and a bunch of big wig suits from out of town corporate got in with him. Hippy dude got out first and walked over to his desk and went to work.
Big wigs went to to local manager's office, and reamed him about this scruffy dude, and he needed to get rid of him.
Well, he did. Told him sorry, but it was out of his hands. Next week, people kept putting their stuff on the guy's desk to be done. Everyone started bitching their work wasn't getting done.
Somehow the manager got hold of hippy dude to come back. Hippy dude said sure, for $4 bucks raise.
The next week he was back and caught up on the backlog.
