How fragile do you have to be offended by a security asking you where you are visiting on a site that he's working at? No amount of money can unlame a lame.
I know a guy who still hates his uncle because 8 years ago, after getting accepted into varsity, he asked him for registration fees since his parents couldn't afford it. His uncle said he had no money, then bought a brand-new car a week later. He got help elsewhere, but never forgave him.
To this day, I still fail to understand why Thabo Mbeki closed down those technical schools and trade schools, only for us to later hear him and others complain that South Africans lack skills.
That's Mrendeni taking the video, he drives a Merc c class brabus and the multimillionaire is George. Their source of wealth is questionable. Gorge runs an internet cafe opposite Tembisa police station and Mrendeni's source of wealth is unknown. X detectives do your thing.
And also, imagine you are a security guard at BMW and someone drives in with these modifications.
I would also ask a lot of questions because clearly this is someone who doesn't like or respect BMW. I'd assume this is someone paid by Merc or Audi to tarnish BMW's image.
