A customer at a McDonald's in Brazil was seen launching into a flying kick toward an employee during a fight in the fast-food restaurant. 

The incident happened at the chain's Sao Paulo location during a confrontation between workers and customers, flying kick. An employee then appears to throw a punch, prompting the man to walk away. 

Other employees attempted to step in as the woman demanded her money back. She is seen picking something up from the counter and throwing it before the footage ends. 

The reason for the dispute was unclear, but local media outlets said it could have stemmed from a food order. 

McDonald’s said it regretted the scenes of violence at its Sao Paulo branch, the Sun report states. 

The fast-food giant said it was investigating the incident and taking appropriate measures.
