Sounds like large tips to me.
I'm sure regulars and the occasional gifts and tips, are important in the business specially now that is so competitive. This thread is about a special kind of compensation that is including someone in your will for him to receive an extra compensation (money, art, car, house) after the passing of his former client.
Someone even talked about a reverse mortgage to pay the services of an escort, let me see if I can find it.
Bingo:
reverse mortgage for escort services
My advice: till when can the client change his will to benefit someone younger and cuter? How long will he be around?
