Have you seen the video?
He had already got away with being a dickhead even after a machete was shown to him. He had safely returned home.
Then he decided It was a good idea to return and continue insulting them, and abusing them specially the female shopkeeper. With kids present.
I’m sorry, he had it coming, he should have seen it coming from miles away, and he is an absolute tool.
Also in a way he is lucky it’s just a broken jaw, he could well have been stabbed and/or killed.
