How many of you get charged by your dentists?

My friend is a DA. Her boss was choked that the work to fix her tooth was done free by him.

He got annoyed right after and hinted to her that next time it’s 20% off for any future work.

She felt uncomfortable right after, especially after assisting him with a patient he wasn’t even clocked on to do (office is closed for holidays, but that patient had come in because of emergency reasons).

Was so surprised. Not a fan of of this dentist (dating a mutual friend), and he’s known for being stingy asf, and slightly less empathetic.
