Ever go up to a stranger and say, 'y'know... you really suck!'?

My brother in law HATES people who aren’t disabled but use the handicap spaces. When he sees someone doing it, he follows them into stores with a fake limp and fake speech impediment, spitting as he.berates them. He’s not disabled, but he is 6 ft 5. Makes the jerks really uncomfortable.
