I think this is the issue. A provider says that she barters Dental Work for Sex.
If a Dentist gets caught with a Hooker in a non professional capacity, it's a Class B Mis. Probably cost him $3000 by the time it's all said and done.
If he gets caught Bartering his Profesional Services for Sexual Favors, he can be brought up on Ethics Charges, and stripped of his means of livelyhood.
Better listen to Charles, he know what he is talking about.
I don't know about Plumbers, Hell, they make more than a Dentist anyway.
