A California man has accused workers at a grocery store of dragging him into a closet and delivering punishing blows after he complained about the long line at a register.

John Valencia, a father of seven, told Fox 13 he went to Stater Brothers on East Baseline Street in San Bernardino to buy some coffee and creamer about 8 a.m. Wednesday.

The line to the only open register was long, so Valencia asked a manager if another checkout lane could be opened but was ignored, he said.

Then “I just went and got in line. I was like, ‘Well, thank you, you know, great customer service,’ ” he told the outlet.

“At no time was I being aggressive, at no time was I being loud, was I threatening him or any way.”

Valencia said that when the manager still became upset with him, ”I was trying to tell him like, ‘You know bro, calm down.’ I just asked you to open another lane,” Valencia told Fox 13.

But the manager allegedly didn’t take too kindly to the comments.

Valencia said he was suddenly grabbed, tossed into a store closet and assaulted.

“Other employees came, and I can remember it was like they had me on the ground, and I seen them trying to close the door, and I was trying to kick the door open so they wouldn’t close it, and they grabbed my legs and pulled them up,” he told the outlet.

“Two of them started beating on me, then they started kicking my face and stomping on my back and stomping my head while holding me down,” Valencia said, adding that someone finally said, “Let him up, let him up.”

A witness captured part of the shocking incident on video.

Valencia said he called 911 and his wife, Meagan Lacey, after the beatdown.

“It was terrifying to get the phone call from him,” Lacey said, adding she could not believe that the woman who filmed part of the alleged incident was the only person to do anything at the time.

“There were so many people in that store and so many employees and so many people that were given the chance to help, and nobody did — she was the only one,” Lacey said.

“I know that she couldn’t have done much physically against all those people, so I’m just thankful that she did record it and that she was willing to share that recording,” the wife added.

Valencia told Fox 13 that he suffered a concussion and that his eyebrow was split open from the assault.  

“I want the people involved to be arrested,” he told KABC. “They shouldn’t be working at Stater Brothers. anymore. That’s not a safe environment with those type of employees.”

His lawyer, Shane Hapuarachy, claimed the attack was “completely unprovoked.”

“This wasn’t a situation that called for violence of any kind. There was absolutely nothing that [Valencia] did to warrant that type of response from an employee of the store,” Hapuarachy told KABC.

In a statement, the business said it was “conducting an internal investigation of the incident and [was][ unable to comment any further at this time.”

San Bernardino police said they had received a report about the incident, which will be reviewed by the county district attorney’s office.
