“She grabbed my daughter and punched her in the face, the back of the head, and then slammed her down on the ground,” Serena’s mother told the outlet. “I’m angry.”

“I was scared because it happened so quickly,” Serena, who has epilepsy, explained. Her mother told KWTX that she believes that the attack could have triggered a seizure.

After the incident, Serena quit her job.

In a statement obtained by KWTX, the owner of the franchise said, “The safety and security of my employees and customers is a top priority. We are working with law enforcement on this matter.”
