Wayyyy back when I was about 45, I was a manager of a small 16 unit apartment complex on Hollywood Beach, we had many young people, the apartments were old and small and not kept up so they were cheap for the location.
Turns out one super hot 20 year who rented from me was an escort and wrecked her car, drunk and stoned. She told me the agency she works for charges $200 and she got $100, had to pay a driver supplied by the agency $30, so she screwed and sucked for $70, she said most guys didn't tip or if they did it wasn't much.
She asked me if I would drive her and I joked each drive was worth $30, if I drove her 3 times it was about equal to what she pockets per pounding plus the dependency and convenience. To my shock, she readily agreed and I was pounding this magnificent hot 20 year old a couple times a week just for midnight rides.
