Screengrabs.

A contentious scene was captured on video that resulted in a white man being punched out.

The video begins with the man kicking at the two shop workers who appear to be trying to kick him out of the business.

The man was removed from the store, but re-entered.

"Keep your distance," warns the older shop worker.

The white man waved his fist in the air, at which point the older shop worker knocked him out with a single right-handed punch. The white man appeared to be unconscious during the final fifteen seconds of the video.
