A young accountant was leaving the office at 4.45 p.m. when he found the Office Manager standing in front of a shredder with a piece of paper in his hand.
"Listen," he said, "this is a very sensitive and important document, and my secretary is not here. Can you make this thing work?"
"Certainly," said the young man. He turned the machine on, inserted the paper, and pressed the start button.
"Excellent, excellent!" said the Manager as his paper disappeared inside the machine, "I just need one copy."
Never, ever assume that your boss knows what he's doing.
