I have done this. When I am in the city walking, when a bum is coming and I get that weird 'feeling' I just know he is coming for me, first thing out of my mouth is, "Scew me sir!, have you got a dollar?" This surprises them so much they just keep on walking. One guy got pissed and yelled, 'That's just what I was fissin' to axe you!" and he kept on walking. The rest of them leave me alone.
