A McDonald’s employee in the UK was reportedly suspended for headbutting a customer after an argument broke out over Chicken McNuggets.

The altercation was caught on video early Tuesday morning at the Liverpool One location of the fast-food restaurant, the Liverpool Echo reports.

The customer allegedly became upset after being told he couldn’t order nuggets because the menu had already changed over to breakfast, according to the Echo.

The incident occurred at around 4:50am.
