Major chains across the country have brought in new rules and equipment to keep staff and customers safe when buying essential goods.
Everything from limiting the number of shoppers through the doors to protective screens and marshals on hand to keep order are being deployed by supermarkets as the coronavirus outbreak intensifies.
Other measures include markings on the floor to help with social distancing, protective gear for staff and encouraging customers to pay with contactless cards.
Waitrose has backed the Government's plea for social distancing with what it calls "a set of strong, new measures" to help its customers shop safely.
The company said the number of customers allowed in at any one time will be limited so that social distancing can be observed, and a "one in, one out" policy will be operated when it is judged that the shop is at capacity.
Customers coming to Waitrose will see marshals who will help to manage queues outside shops and if necessary remind people to respect the two-metre social distancing rule.
Waitrose will dedicate the first opening hour to elderly and vulnerable customers and those caring for them, while NHS staff will continue to be given priority checkout service. There will also be "safe distance" floor signage, protective screens at checkouts, and additional security.
Morrisons, which has already put up perspex screens, is introducing signage in stores to support social distancing, including floor stickers, posters and banners that ask customers to keep one trolley distance apart, as well as giving guidance on where to wait and where to queue.
Lidl said it's installing checkout protection screens across all its UK stores to protect colleagues and customers.
Lidl GB chief executive Christian Härtnagel said: “We hope that this additional safeguard will help to provide extra reassurance for those both working and shopping in our stores."
Sainsbury's said it is "working through the detail" but expects to restrict the number of people allowed in stores at any one time, and will also be introducing barriers outside to ensure people queue at a safe distance when waiting to get in.
The supermarket said it will also have reminders to keep two metres apart displayed throughout stores, screens at manned checkouts, and will close every other payment point to help keep people apart.
Marks & Spencer said trolleys, baskets, screens and all touch points will be cleaned every hour and deep cleaned every night.
M&S said when customers arrive at its food stores, they will see a "greeter" who will ensure the number of customers in the store at any one time is managed.
The stores will have floor markings in queuing areas to remind customers about social distancing and "sneeze guards" will be in place.
Customers will be asked not to scan their Sparks card and cash payments are discouraged.
M&S also said its 31 outlet stores selling only clothing and homeware will be temporarily closed.
Workers redeployed from the clothing and home departments will help support limiting customer numbers entering the store.
