Great Compromise

One day, a man walks into a dentist's office and asks how much it will cost to extract wisdom teeth. "1000 rupees," the dentist says. "That's a ridiculous amount," the man says. "Isn't there a cheaper way?"
"Well," the dentist says, "if you don't use an anesthetic, I can knock the price down to Rs 800." Looking annoyed the man says, "That's still too expensive!" "Okay," says the dentist. "If I save on anesthesia and simply rip the teeth out with a pair of pliers, I can knock the price down to Rs 700."
"Nope," moans the man, "it's still too much." "Well," says the dentist, scratching his head, "if I let one of my students do it, I suppose I can knock the price down to Rs 500."
"Marvelous," says the man, "book my wife for next Tuesday!"
