An irate Livonia man smacked a Little Caesars manager across the face because he didn't like what was on his pizza and was arrested, charged with assault and battery and sentenced to 20 days in jail, according to police.

The attack — which was caught July 9 on the shop's security camera and reported Wednesday evening by WXYZ-TV (Channel 7) — came as a shock to Little Caesars' employees who said they had offered the man a new pizza or a refund.

The incident took place at the store located at 15574 Middle Belt in Livonia, according to a Livonia Police Department post on Facebook.

"I've been doing this for 12 years," Kelsi Beckwith, the woman who was struck, told WXYZ. "Not a day in my life have I ever had a customer lash out at me that bad."

Joseph Thorpe got so angry about his pizza because it had Italian seasoning on it, instead of Parmesan cheese, according to the television report. He returned to the store and slapped Beckwith as she tried to refund his money.

Livonia police released the security video Thursday to the Free Press.

Thorpe, 38, called the store to complain about his pizza, returned to the store, and then threatened to beat up store employees, Beckwith said. She added that she asked a co-worker to call 911, and as she was trying to refund his money, Thorpe hit her.

Beckwith said Thorpe "brought his hand back" and "slapped the crap out of me."

The surveillance video appears to show Thorpe, who is wearing a T-shirt and hat, pounding his fist into his own hand, even as someone walks into the store.

Livonia Police Capt. Ron Taig said authorities were able to track the man down through an eyewitness and other accounts of the assault. He was arrested on July 26. In addition to 20 days in jail, Thorpe was fined $750.
