First of all, you'll never get the full hour, so only pay for half hour
half hour: 40
full hour 60
the girls want to make as much money as possible, so they're not gonna have a gradient of services. it's typically 140 for BBBJ (if offered,) and CFS.
Some girls will upgrade to BBBJ for an extra 20/40
I keep wads of 20's in different pockets. 40 in one pocket to pay the MMS, 120 and 20 in other pocket for FS, then an extra 60 in indidually folded bills to pay for any extras they may offer.
