A crash drew my attention to the other side of the bar. Two men stood facing each other. One man was pointing his big finger at the other, nearly touching his chest. His chin was thrust forward. The other man took a step back and raised his hands, palms forward. I could see his mouth moving as a circle cleared around them. While he spoke I noticed his chin tucked slightly and he leaned forward just a hair. The man with the finger stepped forward. The other man launched himself forward, brushing the pointing finger aside as he did so.
