Rude Security Guard.

This afternoon I went to Usave Claim Street in Hillbrow and I had a plastic bag with a few items I had bought from Spar and then I left the plastic bag with its contents by the entrance of Usave. I then bought 2 items at Usave and then on my way out I put them in the plastic bag I had left by the entrance. On my out I was rudely intercepted by the male security guard demanding slips of the items I had bought. I tried to show him the contents I had in my bad but he was so rude and he told me I'm not going to get my slip back because I'm a foreigner who is acting big in South Africa. I was really let down by this kind of attack and I have been a regular customer at this shop since day one a few years ago but this was my first time to be embarrassed and attacked like this. The security guard is new and he is acting like a macho and has no customer care. He was making fun of me for nothing even when I showed him my slip for the grocery that I bought at Spar he just took it and told me 'go away foreigner'. He is so full of xenophobia and anger. I feel very violated and angry. Please Usave take action before customers start avoiding your shop because of your xenophobic Security guard. This happened on the 20th of August 2020 at around 16:00.
