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.
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.
The clerk stands firm, and the man insists on speaking to the Manager.
The Manager appears and then explains that the hotel has an Olympic-sized pool and a huge conference center that were available for the couple to use.
"But we didn't use them," the man complains.
"Well, they are here, and you could have," explains the Manager.
He goes on to explain 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," the Manager says.
"But we didn't go to any of those shows." complains the man again.
"Well, we have them, and you could have," the Manager replies.
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.
"But sir," he says, "this check is only made out for $50."
"That's correct," says the man. "I charged you $300 for sleeping with my wife."
"But I didn't!" exclaims the Manager.
"Well, too bad," the man replies. "She was here and you could have."
