Yep. I think a lot don't bother sanitising any more, thinking the mask is enough.Yep. Somebody who's hands have been in contact with the virus picks something up and puts it back down. Shortly after you pick it up and buy it.
Or the basket or shopping trolley is the source of contamination. .
Wash hands, sanitise going in the shop, sanitise coming out and don't touch your face.
Also distancing is getting worse imo
