Watch: Unfazed bar patron casually lights cigarette at gunpoint during armed robbery

After a long, hard day, sometimes you just don't have the energy to put up with any riffraff. Such was the case for a St. Louis bar patron earlier this week, who defiantly sat through an armed robbery — even casually firing up a smoke while being held at gunpoint.

What are the details?

KSDK-TV reported that a suspect armed with a "heavily modified pistol" ordered customers to the ground at Berhmann's Tavern shortly after midnight on Wednesday, getting away with a few hundred dollars. But surveillance footage of the incident, shared by The Daily Caller, shows one man was utterly indifferent to the chaos.

The video shows patrons turning around to look at some sort of hubbub, before holding their hands up and dropping to the ground — with the exception of our hero.

That unnamed guest refused to be bothered by the commotion, and continued scrolling through his phone before the suspect tried to steal it. The would-be victim wasn't having it. After a brief struggle, the criminal continued on to easier targets, but repeatedly pointed his firearm at the man, who paused to light a cigarette and refused to leave his seat at the bar.

In the end, the thief got away with some goods, including wallets and cell phones, but not from the guy who refused to be bothered by it all.

According to KSDK, the suspect is still at large, and is described as being in his late 30s to mid-40s. He was reportedly wearing a blue shirt and dark pants during the crime.
