Surveillance footage from inside a McDonald's in California shows a woman filing a complaint to the management... with her fists.

The incident happened after 11 P.M. on October 27th. The woman had gone through the drive-thru and got really mad when the staff apparently screwed up her order by not putting enough ketchup in.

The unidentified customer then entered the restaurant through the employee entrance to complain. The manager told her she couldn't be in the building and she became combative. She started pushing and punching an employee.

A man eventually came into the restaurant and pulled the woman off the manager. The pair left the building and disappeared. Police are searching for both of them.
