Man attacks people in the street with warning triangle

The video is making the rounds on social media. The video shows how a discussion arises between different men. Some waiters also intervene. At one point, one man steps into the trunk of his car and pulls out a warning triangle.

With his warning triangle in hand, he walks over to another man. A passerby tries to stop him and takes the blows himself, after which it turns into a fight.

In the background you can see someone else driving away with the vehicle. It is unclear what led to the incident.
