Rudeness at the Big Pick 'n Pay in Kroonstad

I went in to the store in Kroonstad today to do shopping. When I got to the till one staff member shifted past me not keeping social distance. He was going to the till next door so I said nothing. When another staff member did the same thing I commented. Hey social distance. She laughed at me along with one or two other staff members. I have a mother who is an invalid and is already on oxygen for Emphysema. I cannot bring Covid19 home as it will **** her. I also cannot afford to get sick as I am her primary care taker. My father has to work. I admit I lost my cool when the people started laughing at me and yelled that I am glad that they found me entertaining. I think their behaviour was disgusting and rude. That store has already been closed once because of a Covid19 outbreak. I had a right to be cautious. I will avoid that store like the plague from now on. Rudeness should never be tolerated and there nothing funny about this pandemic.
