One evening one worker tried to leave the plant with a wheelbarrow full of newspapers. The night watchman was immediately suspicious. "Hey, bud," he ordered. "Let me take a look at what's under all those papers." The night watchman diligently looked, but found nothing but newspapers. "You see," explained the worker, "I pick up all the extra newspapers in the lounges and task them to the recycle plant. That way I save a few trees and make a little money."
For the next few months, the worker left every night with a wheel barrow full of newspapers, but the watchman remained alert and checked them every night.
One evening the night watchman was called to his supervisor's office. Without a word of explanation, the supervisor fired the night watchman.
"What! As long as I was on duty, absolutely nothing was stolen from this plant!" "Oh, really."said the supervisor. "Then how do you account for the fact that our recent audit shows that we have lost two hundred wheel barrows?"
