A Tennessee man who complained about his food being cold at a Wendy’s drive thru was doused in hot oil by an employee, police said.

The incident happened Tuesday night around 11 pm at the Wendy’s in Huntingdon.

According to reports, the customer (who wishes to remain anonymous) wanted a refund after he realized that his food was cold. An altercation then occurred and escalated.

According to surveillance video, “the employee left the drive-thru window and went to the cooking area and got a container cup of hot oil,” Walter Smothers, Public Safety Director for the Huntingdon Police Department, said, WBBJ reports.

Holding oil from the french fry fryer, the employee, identified by police as Demarrus Pritchett, “came back, opened the window back up, and threw it on the man that was making the complaint,” Smothers said.

“The young man threw his arm up to shield his face,” Smothers added. “The brunt of the oil hit his underarm, down his side. He had second and third-degree burns, blisters and so forth on his arms.”

The victim was rushed to a local hospital where he was treated for extreme burns and blistering.

Pritchett, 23, was arrested and charged with aggravated assault, according to the Carroll County General Sessions Court Clerk. He has been released on a $5,000 bond.

Pritchett told police that he didn’t know the victim well but that the victim was allegedly “harassing him for the past couple of months,” WBBJ reports.

The victim’s mother said her son is still shocked that the employee threw grease on him.

No word yet on whether Pritchett has been disciplined or fired.
