Scott at the dentist

A Scotsman phones a dentist to enquire about the cost for a
tooth extraction.

"£85 for an extraction, sir"

"£85?", the man replies. 

"Huv ye no'got anythin' cheaper?"

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

"Whit aboot if ye didnae use any anaesthetic?"

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

"Whit aboot if ye used one of your dentist trainees and
still withoot an anaesthetic?"

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

"How aboot if ye make it a trainin' session, 'ave yer
student do the extraction with the other students watchin'
and learnin'?"

"It'll be good for the students" mulled the dentist.  "I'll
charge you £5. But it will be traumatic."

"Och, now yer talkin' laddie!  It's a deal," said the
Scotsman. 

"Can ye confirm an appointment for the wife next Tuesday
then?"
