Funny I was just thinking about this today, working security at large hotel downtown, late at night I will sometimes get several requests from females to walk them around the corner to the diner or down the street to their cars... that said, if I am not working and am walking too close to a female I don't know I will notice them constantly speeding up to put distance between us, even though I'm just a cute skinny white guy I guess I still resemble a threat.
