technology malfuncrtion

At the dentist this afternoon, I am there for the third and final phase of giving me a new crown. But the goddamned thing resolutely refused to cement onto the tooth remnant.
"This is one of the worst mouldings I've seen in years" the dentist sighed, shaking his head. He then has to take new impressions, and once again I must go home with a perfectly serviceable, but still strictly temporary, filling. He was suitably embarrassed about the whole thing, which in truth was a bit of a cock-up.

Thinking quickly on the couch,I made use of the opportunity to confirm my belief in him by ordering some more cosmetic work, and beating him down on the price into the bargain.
