I think what she has presented is fair. She is pitching her market at the man who would not consider seeing anything less than a 'Courtesan', whatever that may be. Beauty and quality are in the eye of the beholder only.
By marketing herself like this, she is helping the more seasoned punter to make an informed decision, and that is not to see her. Simples. It's a win-win situation. She gets the money man, and he gets a lady who charges top dollar
One small thing. She needs to get the whole of the legend scrutinised by someone who is a scholar of the English Language if she really wants to impress the 'discerning gent'
