After a long day of travelling, a husband and wife decide to stay in the nearest hotel.
They go straight to bed and are almost immediately sound asleep.
The next morning, they wake up and ask for their bill.
“That’ll be $300 each,” said the manager.
“WHAT?! Why so expensive?!” demanded the husband, outraged.
“Well, there was the car valet, the swimming pool, the sauna…” responded the manager.
“But we didn’t use any of those!”
“Yes, but they were there, had you wanted them.”
The husband then reached for his wallet, took out $100 and handed it to the manager.
“No sir, I said $300 each,” sighed the manager, shaking his head.
“Yeah but I’m charging $500 because you slept with my wife!”
“I did no such thing,” said the manager, his cheeks reddening.
“But she was there, had you wanted her!”
