Are allowed! Our Pubs are serving ordered meals to be collected or delivered in the village: cooked on the premises by qualified staff and Facebook is full of praise. No one has been infected by anything despite the initial worries. Our village shop remains open with 3 allowed inside at one time. Everyone quite happy. However, so far it hasn't rained

The Government allows us to drive no further than 5 miles. That would get me to the nearest supermarkets but not back

when taken literally

Do look on local Facebook groups and the Trussell Trust as well as local Churches. EVERY area has food deliveries to access now: via pubs., food outlets, food veg. box systems; food banks will advise as should the Church/Chapel, our local shop has had donations both from locals and a country-wide charity which are topping up what the vulnerable here might need in future weeks - the Charity has had a huge input which they are rolling out across the UK.
Ask your GP/Pharmacist/Church if you don't look at Facebook etc.. No one need not have access to food. Our shops are delivering and the Supermarkets too. If you see a small supermarket van delivering locally, wave it down with your details in a sealed plastic see-through envelope/bag and hand to the driver? Or ask the postie as he/she passes by, ours are speaking from a respectable distance.
No one need go without. No one's needs are less important than anyone else's might be.
