varun1234 - I did ask in Sainsbury’s what their policy was for staff, and was told that the cashiers didn’t have to wear them because they were behind screens, but those working in the shop did. It did appear that they were all doing this, and I didn’t see any customers without one either, which was quite impressive. We’re fairly civilised here in the South West - but of course there are always exceptions ! 😀 😷
I bought 50, 3 ply surgical ones from Amazon for £4.99 which is working well. I keep some in my bag, some in the car, and usually one in a pocket, to be on the safe side.
