Police in Glendale, Wis., are currently seeking the public’s help in identifying an irate McDonald’s customer who assaulted a teenage employee after receiving the wrong breakfast order.

The suspect and a friend reportedly pulled up to the drive-thru of the McDonald’s just before 11 a.m. on March 18, where they placed an order for a breakfast sandwich with bacon, according to the Milwaukee Journal Sentinel. But upon receiving a breakfast sandwich with sausage instead, the woman became angry.

“What the [expletive] is this? I didn't order no sausage biscuit,” said the woman, who then threw the food back at the drive-thru operator.

A manager replaced her order with another sandwich, but she and her friend soon returned — this time entering the dining area — and claimed that the order was still wrong.

The woman then proceeded to walk behind the counter to argue with the manager, and ended up shoving a separate 17-year-old female employee to the ground.

The Journal Sentinel adds that the girl hit her head on both the french-fry station and the floor, but didn’t suffer any burns. She was transported to a hospital for evaluation.
