I read about some of the punk kid runaways who aggressively panhandle people places like San Francisco and Portland. They really think they have a right to what’s in your pocket just short of taking it from you. If they weren’t punked-out scrawny kids, they’d probably try that too.
I can’t speak to San Francisco, but I recall some of the youthful panhandlers in Portland, OR as being pretty damned aggressive, and that would’ve been in the mid to late 1990s.
I’ve heard from friends still living there that the streetkid panhandlers are even more aggressive now, just shy of outright mugging people.
I was downtown in KC just out of court walking to my car when a white dude came right up to me, an inch from my face and asked for money. I ignored him but took off my diamond ring at that point.
