That's worrying, hope the friend gets better.
I've just done a small top up shop at a Sainsburys local, skimmed milk, cheese, loaf of bread, some rocket plus a couple of Easter Eggs for my grandchildren as they were abundant and in one's face. To be dropped off without us having contact.
The shop is fairly small, it wasn't crowded when I went in, but got more so when I got to the self service till. There was a mother with 2 children, aged about 8ish, she had brought them in with her which is a shame because together they would have been very visible if they had waited outside. It seems they didn't understand distancing, not at all, several people including myself had to tell them they were too close, they came right up beside me when I was paying.
I know there was a report of a mother recently who had to take her young child to a supermarket and was told to leave him outside which I thought was awful, particularly as it was a large shop and he would have been on his own, the person marshalling should have used some discretion in that case. However, in this instance, the children imo should not have been in the shop.
