In my clubbing days, we had a tour we would do. We met up early at a coffee shop, then once everyone had arrived (usually a mix of 5-8 guys and girls, all just friends), we would head to one of two bars that had dollar nights. Get a good buzz going, and then head to the next bar and then the next. We would add people to our group as we went along and almost always ended up at a gay club for dancing because they played the best music. We did this in Vienna one time and ended up with over a dozen people in our group from Italy, Canada, Switzerland, Austria and Germany. Ahhh those were the days! The thing that surprises me is that they got into a fight in a gay bar. This tells me they may have been followed.
I'm not a fighter, but looked to me like he was holding his own there until he got stabbed. I like how he draws them out into the street and then moves forward, bowling them all over. That must be one of those jujitsu moves he spoke about. Praying he recovers quickly.
