Thought this was fascinating. I can see how many women would be intrigued by a "manservant" who catered to their needs (listening to them complain about their problems, pour them wine, maybe massage their feet).
As the video states, this is not prostitution or an escort service; more the hiring of an individual who caters to your (non-sexual) needs for 1-4 hours at a time.
Would you hire a (wo)man servant?
