Covid19 social distancing

I have been in Pick n pay Soneike and the Liquor store a few times. They don't enforce social distancing with customers accordingly and its actually frustrating that I try to avoid going to that store at all cost because of this. I spoke to the manager and she said she can only enforce it on her shift as they work split shifts? Like seriously? What is this store thinking? I had COVID-19 and recovered, but there are no facts showing that you cannot get it again. I have to go to the shop for essential items and it's frustrating, scary as hell and affects my anxiety so bad. We are in a pandemic, don't people see this? People are dying and last night was the cherry on top for me at pick n pay soneike where I was busy paying and once again the customer did not follow the social distancing rules set by government, I told the cashier to tell the customer behind me to social distane and stand on the red line the cashier then tells the customer "The customer asks can you please social distance" really? I didn't ask, it is the government who put these things in place so that we don't come into close contact with each other not me. Also I just recovered from COVID-19 so it's 10 times more scary having someone close to me. The customer then moved but my issue is why can't the cashier enforce government policies? Also as I walked out of the store I told the manager and a cashier commented to say that I am petty. Like really? These peoples eyes will not open unless they get the virus or people close to them start dying. It's really serious and I want the store owner to contact me. I really don't see why I must drive to another shop when soneike pick n pay is right across the road from my house. They must enforce the law in the store and not have this relaxed attitude! I think I have given the store more than enough chances.
