Was in a supermarket queue this morning a little over 20 minutes. It was snaking down the side of the store beyond the 'theme park' barrier system and down a street. Everyone was 'distancing' a reasonable amount. The lady in front of me was producing huge atomic fumes from a vaping stick thingy and the man behind me was chain smoking roll ups. I had nowhere to go. If I hadn't have been getting a couple of items for my next door neighbour I would have walked away.
I daren't say anything because we were outside - just thought it was rude to smoke on top of a captive audience.
I also thought the protocol was to shop alone? Many shoppers were in pairs/couples? My daughter saw this being enforced in a different supermarket yesterday but in this one no one was batting an eye lid - there were far more people in the supermarket than was necessary because of all the extra 'paired' people.
It would be better if all places followed government guidance to avoid confusion.
