A customer complaining her McDonald's order was wrong was knocked to the ground when the manager through a blender at her.
Shocking CCTV sees the woman fall backward to the floor of the restaurant after the argument escalated.
Britany Price had ordered some Happy Meals but realised her order was wrong so parked up and joined the queue to get the correct food she'd paid for.
The footage shows her waiting, refilling her drinks, and standing out the counter getting increasingly frustrated.
Suddenly the row escalates and food gets thrown over the counter.
The manager then picks up the blender jug and launches it towards the Ms Price.
Speaking to WLWT in Ohio, USA, Ms Price said: "I wasn't the only one that got frustrated, you know.
"Watching the video we see a lot of people that see me and her talking, trying to resolve the issue, and they're, like, 'I'm not dealing with this,' you know.
"They just left. They didn't even place their order."
The woman was left with a broken nose and a shattered cheekbone which needed surgery.
She added: "I've had surgery. I've had a lot of doctor's appointments, the follow-ups."
McDonald's confirmed the manager no longer works for them and the former employee has not spoken publicly about the incident.
