Hank and Gomez are drinking in the shitkicker hole in the wall to end all shitkicker holes in the wall. Gomez is exceedingly uncomfortable. Hank's gotten sullen, and Gomez's complaints just make him grumpier. After some small talk about El Paso (which clearly doesn't put Hank any more at ease), Hanks spies some drunken lowlives who appear to be maybe possibly if you squint engaging in a drug deal. He glowers at them on the way to the (gross) bathroom, whereupon Hank has a bit of a panic attack. You can tell because the music becomes a wall of feedback sounds, while the camera zooms in on his face. BREAKDOWN! WOO! Back at his barstool, Hank can't keep his unhinged, accusatory stare at the two guys. He tells Gomez he thinks they're holding. Gomez is like, "Who ISN'T holding?" But Hank is undeterred. Gomes wants to call for backup or to confirm they're not just messing up a random sting. Now Hank wants to forget it, and heads off to the bathroom again.
In the parking lot, Hank waits for Gomez to return from paying the bill, and he seethes. Just seethes. Finally, he grabs for his gun, before thinking better of it and leaving it on the seat. He marches back to the bowling alley, crossing paths with Gomez along the way. While ZZ Top blares on the juke, Hank strides up to these two burly-as-fuck dudes. "Stand up," he orders, almost inaudibly. They then all make the internationally-recognized hand signals and facial tics that inevitably mean "Let's Fight!" And fight they do. Hank's rage holds its own, smashing one guy's face down on the edge of the bar, while another gets smashed into a mirror. Once Hank has punched them both unconscious, that's when the rest of the barfolk advance on him. "DEA!" Hank squeals, like he's making a legitimate arrest. The mob backs up. He tells someone to go fetch his partner, while about a dozen folks look at him like he's completely locopants. Which he is.
