Digusting customer service

I am am absolutely disgusted and annoyed by the service received from the supervisor in charge on the 20-03-2021. I had a face mask (one of the clear ones) not a face shield but the face mask that covers from the nose. I was with my husband and I was not allowed in and the security said I can buy a mask for R5 but we went back to the car to fetch the surgical mask. Fortunately whilst coming back to food *****s market there was a man who works at the police force who wore the same mask that I was wearing before. He was informed of the same thing and he refused and wanted to speak to the supervisor inside in which we also followed to get clarity on the matter. The supervisor was very rude and said he would not be served at any till regardless and he produced his government badge and informed them of the difference a face shield and clear face mask. The man insisted that he would not leave as this is regarded as a mask and not a face shield which covers the nose, he continued to shop but immediately when we left the area by the supervisor, that supervisor shouted in sesotho directing it to us saying where do we get off in such a rude manner and that was very unprofessional. We continued with our shopping and saw two people with a mask that they placed below their nose they actually were standing by her. So we did the same because it seemed they were allowed to. On the till that we were directed to (till#11), she called from her area far away from us and said 'tell those people to lift up their masks' in such a rude and arrogant manner. Immediately after purchasing we went straight to her next to the people who had their mask down and told her in a polite manner that she can't shout at us all the way from her work station and she should could have come straight to us and told us in a polits manner, yet showing how unprofessional and that she was acting in a punitive manner towards us. She raised her voice at us and we reverted back because she was out of line. She never said anythhing to the people next to her who were not wearing their masks properly then when we left she said have a nice day in a sarcastic manner. These masks are sold at clicks but out of respect we went back to the car to change it before we came in the store but the way we were treated in that store was uncalled for and she clearly has no customer service. We will never shop at food *****s market in Centurion Gateway Plaza. Never again!
