If she is way over west near Cardero and Davie, then she could be a stray/part-timer/non-pimped or a civilian.
A civilian standing on a high-traffic corner waiting for her boyfriend to pick her up – and she wickedly enjoys stopping traffic!

What are you supposed to say to her, “Hi are you working? How much?”
She could scream for the cops, and the man could feel as dopey as the George character in Seinfield.
Instead of standing next to the Starbucks she should be next to Richards and Nelson.
