bad customer service at OK MINI LOTUS RIVER

Good day I am highly disappointed in OK MINI in LOTUS RIVER. First of all myself and my father went to buy a few things. While looking for what we need we noticed staff members including some clients walking without masks which is against the law of the country as it is compulsory to wear a mask when indoors especially when you are working with food. My father then approached the manager which isn't the first time regarding the matter. The clients walking without masks then started arguing with us saying that its not necessary to wear a mask as its a thing of the past well not according to the regulation that was implemented. While at the till the cashier named SADEEKA PETERSEN rudely interrupted my father saying that he should be quiet as we are attacking their clients. Bare in mind that we also clients who are following protocol but we get told to be quiet instead of telling their clients to wear masks because the whole purpose of wearing masks is to protect one another. SADEEKA PETERSEN was so rude and I did not appreciate her tone she had with us. I told her to return my money as I am not doing business with them if they treat their clients horrible. I told her I am going to report her and she blatantly said she does not care she isn't afraid of me and told me she has 10 years of customer experience. Where she got her training makes me wonder because she doesn't know how to handle a customer. I then overheard her murmuring under her mask calling me stupid and made a comment about my religion saying something in afrikaans about us just coming out of church. I felt attacked and very disappointed in the service as well as the staff. Even though her manager told her to be quiet she did not even listen to him she said " NO FOR WHAT". I am very disappointed in this service and will never be going to that shop again.
