I would say that in the high end spas, the girls get none of the door fee. That is why it is a separate charge from the room. The spa makes their money from the door fee, and then the MPA can do business with you in the room, and will get the full amount of the NR or BS. Both the MP and the MPA are happy at the end of the session, both making money.
That is why these girls that are fully booked at a top MP, are making some serious $$$. For example, a 6 hr shift, fully booked, is 12 half hour sessions. The MPA won't lose money, because in a one hour session, the prices are simply doubled for the room fee (ex-bodyslide is $100 half hour, $200 full hour).
So, every time an MPA works a 6 hour shift, and let's say for arguments sake, she averages out to a nude reverse massage every time (even though she will get BS and nude). That means she is making $120 per hour on average, for a total of $720 per shift. This could be more if she is getting all bodyslides ($1200 per shift). If she works three shifts a week, then you are looking at an average of approx $2100.00 per week, and $8500 per month, and $102, 000 per year, all for working 18 hours a week. Now that is some serious cash. Beats my job. Maybe I'll have to start working at top MP. Any openings ?
