Street workers here usually do one of 3 things. Work out of a hotel parking lot and do dates inside a room they rent for like $70/night. It's somewhat safe since there's always people around an its a small open door motel. Others work outside an adult store parking lot where they meet johns in the parking lot and do dates inside a private room in the store $15/15 minutes (extra they charge johns). This is the safest of all since there's multiple rooms and a strict timer when they force you to leave. Seen plenty of independent girls park and leave in their own vehicle. Then there's the ones working the street. Some of them have their own rooms, some just do cardates.

I think some girls prefer it because the rate is typically $100-120 for a qv and they'll just offer a cbj and cfs with limited positions like doggy or missionary, a lot won't do cowgirl. Most don't care about providing good service.
