Black customers turned away while white customers served at SPAR. Is SPAR ******?

I am a regular customer at SPAR. This is the second time I get turned away at SPAR Fairlands in Smit street before 8PM during the week. I was there 3 minutes before 8 and the doors were closed. All I needed was milk and eggs. The Security guard acknowledged that it was 3 minutes before 8 but said that they were closed. He turned to the manager who responded by saying “Tell them to go, we are closed” then he turned his back towards the door. The tills were not closed and white customers were being served. I guess I was not allowed in because of the color of my skin judging from the white manager’s response. Their closing time during the week is 8PM. Why advertise it as 8PM when they closed before 8PM. 2 black customers are turned away while white customers are still being served in the shop. This isn’t a surprise after seeing what happened at SPAR Robindale about 2 years ago. I suppose that this is policy at SPAR This is pathetic service as usual from SPAR. I will stop spending my money at SPAR from now on as they clearly cannot understand or spell “customer service”.
