A husband and wife are traveling by car from Key West to Boston. After almost 24 hours on the road, they're too tired to continue, and they decide to stop for a rest. They stop at a nice hotel and take a room, but they only plan to sleep for four hours and then get back on the road.
When they check out four hours later, the desk clerk hands them a bill for $350. The man explodes and demands to know why the charge is so high. He tells the clerk although it's a nice hotel, the rooms certainly aren't worth $350. When the clerk tells him $350 is the standard rate, the man insists on speaking to the manager.
The manager listens to the man and then explains the hotel has an Olympic sized pool and a huge conference center that were available for the husband and wife to use. He also explains they could have taken in one of the shows for which the hotel is famous. "The best entertainers from New York, Hollywood and Las Vegas perform here," explains the manager.
No matter what facility the manager mentions, the man replies, "But we didn't use it!"
The manager is unmoved and eventually the man gives up and agrees to pay. He writes a check and gives it to the manager. The manager is surprised when he looks at the check. "But sir," he says, "this check is only made out for $100."
"That's right," says the man. "I charged you $250 for sleeping with my wife."
"But I didn't!" exclaims the manager.
"Well," the man replies, "she was here, and you could have."
