Every person has a CPF (Cost Per Fuck). A person's CPF is equivalent to the total amount of money you've spent or must spend on them in order to have sex with them. A respectable person has a CPF somwhere around $100. You may include $8 per hour for time spent as well as 40 cents per mile for any driving expenses incurred.

"Umm... no of course not. I mean, I swipped my card for you at the Caf a couple times and paid that cab home from the bar. Your CPF is almost $50. It's nothing to write home about but I can assure you I've done worse." - Loul
