The bartender seems to be buying your version of things, he is clearly appreciative that someone is on hand to explain the bloodshed as well as deal with it so that he doesn’t have to. He helps Sam clean himself up as Snow works on the kid, getting the bouncer to move him to the floor so she can work easier.
In spite of the show, the damage to the A-kid is not very serious. The most dangerous parts, the blood loss and the internalized chip, are dealt with by Snow with minimal fuss, a testament to her healing skill. The seizures stop, but the kid is out, she notices an activated CrashCart monitoring device on his wrist, so there should be someone coming to get him very soon.
The other ganger, Jim, is helped out of the booth and brought to the bar. There he is plied with hydration and starts to become more cognizant, ready for questions.
