It's a Dangerous Business, Walking Out Your Front Door

Let's just say you're walking down the street, its Saturday morning, 11am, sunny, but there's a chill, and let's just say, for the sake of argument, that you pass a prostitute, waiting in a bus shelter, waiting to be picked up, and not by the bus. Now, let's just say that you're walking past her, when she shouts out "You can have a go for free." If there's no one else around, and you assume she's shouting at you, bear in mind that she is proper ugly, missing teeth, hair like straw, garish red lipstick, IV drug user, do you take it as a compliment? Discuss.

Yes, this did happen.
No, I didn't take her up on her kind offer.
