Rude security gaurd Pnp liquor Viking Cape Town

I always go to them since the open about a mont ago and I always go in with my back pack because it is my bag and the security has always let me in but on the 12/03/2021 the Coloured security gaurd that is so rude to all the customers would not let me in because of my bag and the more I told him it serves as my handbag(has) all my valuables in he argued with me and he had no manners what do ever, I am the third customer he has an attitude with and when I asked for the manager no one came just shows how they treat their customers
