I like how the hipster to the right had no reaction whatsoever.

They both should be charged with something or other - he more severely. She tried to get in the way as he tried to squeeze between the other women, using his hands to grab the bar to gain balance. She then turned around with fist upraised, threatening to use it. He grabbed the fist and pushed it into her body, she tried to kick/knee him in the groin and then threw the "punch", and he threw the haymaker. Both idiots and both should be charged, but what did she think was going to happen if she tried to throw hands at some random stranger?
