No Harm No Foul Diver3729?
Not sure what "crime" or violation has occurred at Sun Spa. So what if the person you thought was a woman turned out to be a man?
First of all Diver3729, if you tried to tell the police that you wanted a massage with a happy ending that is admission of a crime in itself. Second, you cannot have a valid contract or complaint that is prosecutable if it is for illegal services. Plain and simple.
Second, let's assume for a minute, that you didn't want a happy ending. You just wanted a massage? Well, there is nothing in these places that promises a woman. It is just assumed. So even in this case there would be no basis for a complaint. Especially given the new LGBT laws. If you don't like the service, don't give them your business.
The only thing that might occur here is a claim that they are operating a massage service without valid lic. It has nothing to do with the gender of the person providing the service.
