"Rent Check" joke

A businessman met a gorgeous girl and offered her $500 to spend the night with him, which she accepted. Before leaving the following morning, he told her that he didn't have any cash with him, but would have his secretary make out a check and mail it to her, calling the payment, "Rent For Apartment".
On his way to the office he began to regret what he had done, realizing that the entire event was not worth the price. Instead of the promised $500, he had his secretary send a check for $250 and enclosed the following note:
Dear Madam,
Enclosed is a check in the amount of $250 for rent of your apartment. I am not sending the amount agreed upon because, when I rented the apartment, I was under the impression that:
It had never been occupied;
That there was plenty of heat;
That it was small enough to make me cozy and at home.
However, last night I discovered that it had been previously occupied, there wasn't any heat and it was entirely too large.
When the girl received the note, she immediately returned his $250 check with the following note:
Dear Sir,
First of all, I fail to understand how you could possibly expect a beautiful apartment to remain unoccupied indefinitely. As for the heat, there is plenty of it, IF you know how to turn it on. Regarding the space, the apartment is indeed of regular size, but if you don't have enough furniture to fill it, please do not blame the landlady.
