Britney is right.
Use you imagination with this one. You can assume anything to answer this question, but stick to the facts offered.
The boss of a storage warehouse had just arrived at work when one of his employees burst into his office. The man explained that while asleep the previous night he had dreamed that one of the stored boxes contained a bomb that would explode at two p.m., causing a terrible fire. The boss was skeptical, but agreed to investigate. After a search, a bomb was found in the area foreseen in the man''s dream. The police were called, the bomb defused, and a tragedy averted. Afterwards, the boss thanked the employee sincerely and then fired him.
The sacked man had not planted the bomb, and his prophetic dream had saved the warehouse from destruction. Yet the manager was right to fire him. How could that be so?

The first reason: The employee is the warehouse guard, who must not sleep while on duty (and must not fall asleep so deeply that he can have a dream).
The second: The bomb was planted by the boss, who intended to get assurance compensation.

this question is too popular
