Went to do my week's shopping at Waitrose this morning. We were there a good 20 minutes early and thus managed to be in the first tranche let in at 7.30, It was one person per shop. DH and I got in together because I was shopping for a friend as well as myself. Once the required number were counted in it was one out one in. It was all over 70s and anyone who wasn't was challenged. An NHS worker showed their pass. Queues at the tillspaced themselves out and evryone did everything by the book.
A number of people have said that masks and gloves are useles. They are wrong because they are not thinking outside the box. A mask stops you touching your face with your gloved or ungloved hand during your shop, it contains your sneezes and coughs instead of coughing into your sleeve, which can then spread your bacteria/ if you brush against anything, or getting out and using a paper tissue, with no receptacle immediately adjacent to throw it away,and you can then use sanitiser on your hands , but it is very complicated mid shop. Wearing a mask takes awy all those problems.
Similalry going round a shop where you are constantly handling packets and tins, which could all, theoretically be covered with the virus, that virus load is on your glove not your hand, strip your gloves off when the food is in the car, and if you are really worried leave the food in the car for 24 hours or wipe it when you get home, but there is no point in wiping it if you have shopped bare handed and wiped your hand all over the car before getting in and handling your handbag and lots of other things getting your hand sanitiser out and using it.
None if us is going to have the perfect sanitisation system. You would have to seal youself into aplastic bag for the duration to manage that ( and doing that would also pose other life threatening problems) but I do think that if you shop you should, so to speak, gown up.
