A matchmaker approached a single woman and told her he had a husband for her.
"I'm ashamed to bring this up," he said, "but the man wants to be sure you are compatible in bed. He wants, he says, a sample."
The woman was shocked. "Such a thing you ask a virtuous woman? Such a crude person would suggest such a thing?"
The shadkhan, trying to earn a fee, said, "He's a business man. He buys goods in the market and he sells goods. By him, it's not a big deal, a sample."
She thought a minute. "He's a business man? So tell him I don't give samples. If he wants, I can give him references."
