Sexually harassing a woman at a bar was the perv in this video’s first mistake, but his night quickly got a whole lot worse when he then lashed out at a bartender.

The incident took place in the wee hours of the morning at a Russian bar in October of 2015, and was captured on the establishments CCTV system.

The footage begins with the troublemaker in the black shirt leering at a blonde-haired woman and then patting her on the backside as she walks past him.

She reacts angrily to the unwanted sexual harassment, turning around and shouting at the man, who appears to just ignore her as he leans back against the bar.

The woman complains to a nearby bartender, who taps the lout on the shoulder and presumably tells him that he’s acting inappropriately.

Again the man, who’s almost certainly drunk, appears unapologetic and at one point just nonchalantly turns his back to the bartender, though soon after he starts talking to him again.

Things start to get more heated and the bartender takes the man’s drink out of his hand and confiscates it.

The drunk doesn’t look like he’s in the mood to leave quietly though and the bartender appears to swipe at his face, though there’s minimal contact.

There’s a brief moment of calm before the storm, and then the altercation escalates swiftly as the drunk suddenly lashes out at the bartender with a straight right.

The bartender reacts furiously to that, leaping up onto the bar and then launching a flying kick at the lout’s chest, which drops him hard to the floor, then follows up with a single right hook afterwards to seal the deal, before walking away.

The video serves as a reminder that on a night out you would be wise to keep your hands to yourself, as inappropriate touching and / or raising a fist in anger is a sure-fire way to get yourself into the kind of trouble that you’re going to regret in the cold light of day.
