I did a similiar thing a few years back. I was in Hong Kong, on a beach, that looks over to PRC beyond the straits.
Some punk kids were throwing bottles on the rock rip-rap, and all the broken glass was showering onto the sandy beach. Being extremely pissed, I walked over to the punks, lifted one up by the shirt collar, and yelled into his face "Do you know how f##king lucky you are to live here, and not over there?"
Slammed him down on the ground, as they looked at me in amazement, having no clue what I said.
But I felt better!
