I remember a regular of mine who was always booked out.

Really pretty girl late twenties.

The reason she was booked out was that her regulars would book her for hours. One guy 3 hrs, me 2 hrs and so on.

Some guy would book her and take her to dinner. So she didn't see that many customers per day but had the hours clocked.

Unfortunately she no longer works and i think a regular took her off the market
