Authorities said the attempted robbery happened around 1am on April 28 at an Oak Grove Plaid Pantry in Portland, Oregon

A convenience store cashier in Oregon taught a would-be thief why it's a bad idea to bring a knife, or a hatchet, to a gun fight.

Police released surveillance footage on Friday of an attempted robbery that took place around 1am at an Oak Grove Plaid Pantry in Portland, Oregon.

The video shows a mask-wearing robber pacing on the sidewalk outside of the store before entering and approaching the counter.

He pulls a hatchet out of his pocket as he confronts the cashier on duty. Seconds later, the cashier calmly pulls a handgun from his own pocket and aims it at the stunned robber.

The robber drops to his knees and apologizes to the clerk

The unidentified suspect sets the hatchet down on the counter before raising his hands in the air. When the cashier pulls out a phone to call police, the robber drops to his knees and starts apologizing.

'I'm sorry. I'll leave,' he says, according to a statement from the Clackamas County Sheriff's Office.

Moments later, the suspect took off running out of the store and away from the scene.

Police arrived later with canines to try and track the humiliated robber, but they couldn't find him.
