He reached the tipping point.

A hotheaded Missouri Domino’s delivery driver was nabbed after allegedly running over a customer who stiffed him on a tip. 

Zachary Nicholus Walton, 36, was arrested Wednesday night after a routine drop-off in Fulton spiraled into a heated, caught-on-camera confrontation.

Walton unleashed an expletive-laced outburst over being left empty-handed and plowed his car into a customer in their driveway, according to court documents obtained by Fox News.

The irate pizza courier was captured on surveillance video blasting the victim and a witness for being “f—king rude” after they dodged the gratuity, causing tempers to flare, police said. 

Walton then allegedly needled them, raging, “What are you going to do, b—h?” Come get me,” before heading back to his car.

The short-tempered delivery man was leaving the home and nearly fully reversed in the roadway when the victim started walking along the driveway.

Walton then shifted into drive and gunned it forward, striking the victim, court docs show.

Police said the victim, who was knocked onto the car, was not preventing Walton from leaving.

They suffered a hand injury, shin scrapes and lingering pain from the impact.

Cops said Walton, previously jailed for domestic assault and false imprisonment, bolted from the scene and was later found at a local Domino’s, where he allegedly copped to charging at the victim to “scare him.”

He was charged with two counts of first-degree assault, two counts of leaving the scene of an accident, and armed criminal action, according to the Callaway County Sheriff’s Office.

Walton is currently being held behind bars without bond.
