So pretty much what they said in Scotland last week.
Was in Asda this morning (with DD which is against the "roolz" of MN), probably bout 20% of people wearing a face covering. Mix of scarves, bandanas, surgical masks and those filter masks which builders wear. Other 80% not bothering. Although everyone was observing social distancing and behaving themselves.
I won't be wearing masks, it's the height of hayfever season and my face is itchy and uncomfortable enough without a mask adding to it. I'd scratch, fuss and fiddle with the damn thing, rendering it pointless.
Asda aren't slow to miss a trick though, selling packs of disposable paper/thin fabric face coverings at the place where you pick up your handheld scanner. 2 for £2.50.
