People like this have far more discipline and respect for others than I'll ever have. I'd be that guy who kicks them in the crotch and push them into a passing bus because they dared to threaten me.
One time I was commuting and a girl in a school uniform in front of a church is asking a boy for money and refused, and she bit his arm and the boy is not fighting back and he looks like he's about to cry. And after like a few months I heard that the same girl was hit by a car and died. I don't know why i just shared that.
"NO, YOU'RE GETTING MUGGED!"
"AH, HOW DOES THAT EVEN WORK?!"
'No. Give me YOUR money.'
