Because I'm white?

<p>My wife and I visited the Pick 'n Pay in Centurion Mall today at/around 16:40 . The store wasn't really busy and we were second in line. The cashier was busy helping the lady in front of us. When she finished helping the lady in front of us she ignored us outright and started helping the gentleman behind us. It was as if we were ghosts, non-existent. Seeing that the cashier, the lady in front of us and the gentlemen behind us were black and we were the only whites, and considering the way in which we were completely ignored, we reasonably concluded that we are not worthy to be assisted because we are white, and so we left. Pick 'n Pay Centurion Mall will not see us again as it was made very clear that we are not welcome there. </p>
