A husband and wife are traveling by car from Key West to Boston.
After almost twenty-four hours on the road, they're too tired to continue, and they decide to stop for a rest. They stopped at a nice hotel and took a room, but they only planned to sleep for four hours and then get back on the road. When they checked out four hours later, the desk clerk handed them a bill for $350.
The man exploded and demanded to know why the charge was so high. He told the clerk that, although it's a nice hotel, the rooms certainly are not worth $350. When the clerk told him $350 was the standard rate, the man insisted on speaking to the Manager.
The Manager appeared, listens to the man, and then explained that the hotel has an Olympic-sized pool and a huge conference center that were available for the husband and wife to use.
"But we didn't use them", the man complained.
"Well, they are here, and you could have," explains the Manager. He went on to explain that 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," said the Manager.
"But we didn't go to any of those shows," complained the man again.
"Well, we have them, and you could have", the Manager replied.
No matter what facility the Manager mentioned, the man replied, "But we didn't use it!"
The Manager was unmoved, and eventually the man gave up and agreed to pay. He wrote a check and gave it to the Manager.
The Manager was surprised when he looked at the check. "But sir," he said, "this check is only made out for $50."
"That's right," said the man. "I charged you $300 for sleeping with my wife."
"But I didn't!" exclaimed the Manager.
"Well," the man replied, "she was here, and you could have."
