I give my dentist a free shop every time I am there.
My report was the last straw for one of the hygienists. She got fired after I reported back to him. Apparently, I was not the only one who was less than impressed with her.
No joke, she said, "Your teeth are so white, I don't need to polish them." She had somewhere to be because she was out of there before I had finished at the front desk.
I told the dentist later. He, himself, polished my teeth. He probably hasn't polished anyone's teeth since USC dental school.
