yep agree to both posters - $100 is the general norm
and icegod is spot on here - it does not automatically equate or upgrade you to diamond its very much YMMV so just respect the girl as long as ur still getting sex
I have had diamond things not done like CIM despite asking for FS similarly i have also had diamond things done for no extra costs after few repeats with the girl - really a case of YMMV and that adds to the adrenaline of punting at RnT places
