A beef over a food order mix-up sparked a vicious, seven-person brawl inside a Texas Whataburger last week, according to reports and authorities.

Police were dispatched to the San Antonio Whataburger just after 3 a.m. last Sunday in response to the wild melee, the San Antonio Police Department told KSAT.

After cops arrived, they learned an order mix-up caused the fight to erupt among two groups of patrons, authorities said.

A viral video posted to social media after the incident captured separate fights breaking out within the group, where individuals were seen pummeling and kicking others to the floor.

Pictures of the aftermath showed blood covering the booths and floor of the fast food chain.

Seven people were arrested and charged with assault causing bodily injuries, cops confirmed to the outlet.

Arrested were Andres Garcia Cardenas, 21, Tyrone Tolliver, 21, Miguel Torres, 57, Meili Torres, 21, Andrew Lopez, 21, Deontae Tolliver, 23, and Veronica Valdez, 53, authorities said.

Two 18-year-olds and two 20-year-olds were also a part of one of the groups, the outlet said.

“Part of another table’s order was mistakenly brought to my son and his friends. Instead of the staff acknowledging their error, they reportedly told the other customers, ‘They have your food,'” mother Rebecca Noel posted on Facebook alongside a video of the fight.

“Moments later, those individuals confronted my son and his friends, and within seconds, the situation escalated far beyond a simple misunderstanding — to a violent assault,” Noel said.

“There is absolutely no excuse for what happened. This never should have escalated to this point,” she continued.

The exact narrative described in the post has not yet been confirmed, but police told the outlet that the video is a part of their investigation.

No major injuries were reported despite the chaos, police added.

The investigation into the incident remains ongoing.

Whataburger, the San Antonio Police Department, and Noel did not respond to requests for comment from The Post by the time of publication.
