A heated argument between a pair of customers and a foul-mouthed manager at an Arizona Del Taco has gone viral. And now, the manager reportedly has been fired by his father who owned the place.

It's unclear how the argument started -- both sides were agitated by the time a woman in the passenger seat started recording -- but the couple apparently didn't get everything they ordered.

They warned him that their video could get him fired or even get the restaurant shut down.

"Where you going to post it, YouTube? No one's going to [expletive] see it," the manager said.

Although he was fed up with customers, the manager said he wouldn't quit the job because the restaurant, owned by his father, was his "pot of gold."

“This is my [expletive] fortune right here," he said. "Why would I quit? Do you know how much of a pot of gold this is?”

After multiple people shared the video on Del Taco's Facebook page, the company said it was appalled.

"We strive to provide a positive guest experience at all of our restaurants and were appalled by this behavior as it is not representative of our high guest service standards. We took this incident very seriously and addressed it with the location’s franchisee, who took definitive action by terminating the employee immediately."
