I feel sorry for the OP she went into the shop to get paracetamol, and something else, the nosy assistant asked if she was OK, the op was honest and said she had tested positive for covid, the assistant then proceeded to tell her off which is not her place, she is there to serve. I would have just said yes, paid for my goods and left. This assistant in my opinion was looking for a argument and to have a go at someone.
Teaching staff and hospital staff are told if they have covid so long as they don't have a temprature and they feel OK they can go in. So why are posters upset with the OP.
I would also add, that some people don't have husbsnds, partners or people to help them, what are they supposed to do starve or continue to be in pain?
