This video was made by a YouTube channel in Brazil that pranks people for doing illegal or unethical stuff. Look for Canal Boom on youtube and you’ll find more such videos. Unfortunately, people do this a lot in Brazil. They park in a disabled spot without being disabled. This was in front of a mall where it’s common for that to happen. And he was just one random guy that parked there when they decided to do the prank.
