Same with my local one when I went at lunchtime. Only difference I noticed was a sign at the till advising certain products (soap, hand gels, toilet roll etc) were limited to 3 per person.
Sainsbury’s in Clapham was chaos this morning, people queuing out the door before opening and when they got in there was a mass stampede towards the toilet roll aisle.
I ended up doing a bit of a supermarket crawl this afternoon, whilst (unsuccessfully) trying to seek out a particular brand of facial moisturising cream - which I couldn’t get hold of although I don’t think that was Covid19 related.
My local Sainsbury’s was very busy, and not a toilet roll on the shelves, as well as the lack of hand gels and pasta. By contrast Waitrose was pretty civilised, didn’t seem to be any restrictions on anything and they even had a reasonably plentiful supply of liquid hand soap (not gel), and even the toilet roll aisle was only half bare.
Definitely a strange atmosphere, people visibly more aggressive than normal, and saw a couple of minor squabbles in Sainsbury’s, mainly over people getting in each other’s way.
