That's great.
Reminds me of what my Dad did to a mugger outside my old building in 1998 just before I left there. He came to the lift, having vanished for a while and had blood on his knuckles ~ apparently, someone tried to mug him and Dad punched the guy full in the face, breaking his nose.
According to the security guard: "When that
madala [term for an old man] punched the guy in the nose, he dropped, got up and ran away."
He's probably still running.
