Just back from my weekly trek round Asda to do the shopping. Got hissed at by some woman because I bypassed the queue of people waiting in a (socially distanced) queue to spray and wipe their trolley handles.
I never bother, I have never bothered. Seems utterly pointless. Rates of Covid in my area sitting around 100 per 100,000. That's 0.001%. Even if you believe that 90% are asymptomatic, that would be 1000 per 100,000 or 0.01%. You'd have to be very unlucky for one of the 0.01% to be the person who had the trolley before you.
Then, that person would have had to be not wearing a mask (mask compliance in this town is very high), sneeze/cough/lick the trolley handle (removing their mask to do so), and then i'd have to smear my hands exactly where they'd licked, remove my own mask, and lick my fingers.
A somewhat unlikely scenario.
It's all about the supermarkets trying to show how "covid secure" they are, isn't it? And actually, it makes bugger all difference?
