Thriftness

A Brit phones a dentist to inquire about the cost for a tooth extraction.

"$85 for an extraction, sir" the dentist replied.

"$85! Haven't you got anything cheaper?"

"That's the normal charge," said the dentist.

"What about if you didn't use any anesthetic?"

"That's unusual, sir, but I could do it and knock $15 off."

"What about if you used one of your dental trainees and still without an anesthetic?"

"I can't guarantee their professionalism and it'll be painful. But the price could drop to $40."

"How about if you make it a training session, have your student do the extraction, with the other students watching and learning?"

"It'll be good for the students," mulled the dentist. "I'll charge you $5, but it's going to be very traumatic."

"Oh, now you're talkin' laddie! It's a deal," said the Scotsman. "Can you confirm an appointment for the wife next Tuesday then?"
