Getting back to the original point of this thread: my MP has passed on a response from Sainsbury's who advised her that, inter alia, they are " ... regularly reminding customers to keep to a safe two metre distance whilst using the pumps." Well, I know they are NOT !!
Mention was also made of their provision of sanitisers and gloves on forecourts - I wish! Again porky pies.
This is not me just having a go at Sainsbury's: other fuel outlets are no better. No one seems to have twigged that fuel station pumps actually provide a ready pathway for pathogens to be shared and, as lock-down is eased, that it will become an increasing hazard !! May I suggest that you don't "Stay Alert" and that, instead you "Don't Forget".
As it stands however, "Stay Alert"
