ASDA is employing 1,000 new Covid marshals, including at its store in Eastbourne.
The store will introduce the marshals on its doors to make sure customers adhere to the Government’s guidelines over the pandemic.
The Asda Safety Marshals are set to be stationed at the front of every store and in the aisles of larger stores.
Bosses said they expect the staff to be able to help shoppers with safety questions and to reiterate Government guidelines.
If customers are not wearing masks in store, they will be told they can buy a pack of disposable masks and pay for them as part of their shopping trip.
Extra hand sanitiser stations will be provided in the busiest parts of the stores and protective coatings will be applied to all basket and trolley handles.
All Asda store workers will now wear a covering while at work unless they have a medical exemption, the supermarket said.
Anthony Hemmerdinger, chief operating officer at Asda, said: “We know that safety remains a key priority for our customers and we will continue to do all we can to keep them and our colleagues safe in store, as we have since the start of the pandemic.
“These additional measures will make our stores an even safer place to shop and work during the coming months.”
