fezzesarecool I work on a supermarket checkout, not a job we can opt to do from home!
On each till we have J-cloth type wet wipes, spray bottle of cleaning fluid and a roll of paper, but not antiviral cleansers. I clean the touchscreen, scale, belt and every part of the till that I, or customers or children can touch, the 'next customer' dividers and the card reader keypad. I've always taken my own hand gel anyway, I wash my hands before starting my shift and use gel whenever I've handled cash or loyalty cards. Obviously everything I'm scanning was placed on the belt by the customer, and I don't know what their toilet hygiene is like, let alone their cough and sneeze habits, or what else they've touched since they last used soap. People will rummage in a wallet for their loyalty card and hold it in their mouth while putting their other cards back, then hand it to me as if their lives depend on their bloody loyalty to the store, it's revolting.
I don't think there is any likelihood that the employer will either provide or endorse the use of gloves at the checkout.
Supermarkets are full of things people just love to handle, loose fruit and veg can (and should) be washed, of course, but you can't wash all the loose bakery products, the baguettes standing in bins at just the right height to catch coughed or exhaled droplets, bread that customers squeeze and poke before selecting a different loaf! Ugh...
