This story is from a dentist friend of mine, and illustrates that they, as well as we in the medical profession, should be careful about finding ourselves alone with female patients.
He was working one day on a young, and very elegant lady. He had placed the local anaesthetic, and as is his practice had sprayed a little topical anaesthetic to the mucosa prior to injection. He was waiting a minute or so for the injection to take effect and his assistant had had to leave for a few minutes, leaving the two alone.
The lady asked if she could rinse her mouth as the topical spray had left an unpleasant taste in her mouth. The dentist handed her the mouthwash and pointed to the receptacle for her to spit the mouthwash out.
She fixed his eye with hers and smiled. “Oh that’s all right” she said, “I don’t spit, I swallow.”
