Yes - changed my mind in the last 24 hours. I've just been in Sainsburys - Winchmoor Hill. None of the staff seem to understand about keeping 1m apart and few of the shoppers do either. I saw staff chatting in groups with each other. Very worrying when you see the older people in there.
Interestingly the Argos branch in the store were well organised. I guess it can be done but too many people are too dim or absent minded.
Likewise I wanted to go for a walk. The streets I would have walked on are generally quiet but packed today. I doubt you would keep a 1 m distance however much you tried as everyone is mingling, plus family groups taking up the whole pavement.
Sad, but this is why we cant have nice things.
