I'd say people have been getting restive about the social distancing rules here for at least a couple of weeks now, I'd say about a third of the people in my Asda on my weekly shop aren't bothering at all now, charging around and being inconsiderate, and aggressive if you challenge them. The floor signs aren't very obvious/easy to follow, so people have always just ignored or not noticed them. Yeah I expect it's going to get worse with people having less time. I've always been in the minority wearing a mask, it's been around 10 % only. Rural/small town area though, not a city, where the Asda is. It will be interesting to see if more people wear them now, and whether people can get hold of them. I last shopped on Wednesday, in Tesco briefly for things I hadn't got in Asda, and their floor signs and aisle spacing was better (bigger store), but I reckon it's largely down to individual store managers how vigilant/organised they are, and how well supported/protected the staff are. I was glad to see more of them wearing full face plastic visors in Asda this week. A supervisor told me they stopped telling people to follow the floor arrows because they were being subjected to so much abuse
