assume the sw is out to steal from you and with that in mind:
- don't park where they tell you to
-don't give them any money up front or even show any money
-make sure your glove compartment is locked and there is NOTHING loose that can be grabbed.
-if their hands are not visible assume their hands are feeling around for something to steal, they will ask for it from behind just so you can't see their hands while they are rifling around for something to steal.
-if you have a wedding band or decent watch take them off and lock them away.
-if you have a jacket in your car assume that it will get riflled through

these girls are professional thieves, adult services are just their cover.
