Serena says while angry words were exchanged, she certainly wasn't expecting the customer to physically assault her. 'I was scared cuz it happened so quickly.'

Serena's mother, Rachel Howell told Fox 6 the customer 'grabbed my daughter and punched her in the face, the back of the head, and then slammed her down on the ground.'

She says she's 'angry' because her daughter has epilepsy and the incident could have triggered a seizure.

The customer fled the scene before police arrived. The man she was with reportedly got a refund for the food. Neither one has been located by police.

In a statement, the McDonald’s franchise owner, Dion Conn, says the location is working with law enforcement regarding the case.

"The safety and security of my employees and customers is a top priority,” says Conn.

In the meantime, Serena has quit her job.
