Ill prob be contradicted for trying to point out my interpretation of the difference between an escort (a genuine one) and a prostitute again but......
I see an escort as a professional lady,usually of class,who provides a service that she will get some form of enjoyment or thrill from too(a very frequent client who has obvious issues with being "addicted" probably holds less appeal than the ladies fascination with cash........she could choose to vary her clients and accept bookings from new clients and still maintain the same revenue............so less likely to "fleece" a client purely based on financial reasons)
A prostitute (regardless of whether they call themselves an escort) in my eyes is the woman with less regard for the quality of service or the clients dwindling bank balance ,than she is about quantity of appointments and not looking or caring where the next payday comes from.(Very likely to "fleece" anyone that is fleeceable)
Escorting is the "oldest profession" and entails some attention to detail
Prostitution is a service provided that incorrectly gets the term profession tagged on by the masses
(Expecting at least some accusations that im deluding myself...so bring it on)
