As the nation deals with the ongoing coronavirus crisis, many supermarkets have had to adapt and change the way they operate.
Shopping is also a totally new experience for customers, with strict social distancing rules and safety measures in place across all stores.
At first, many supermarkets changed their opening hours to allow employees to restock and sanitise stores as stockpiling soared at the beginning of the pandemic.
Over time, however, this has thankfully calmed down, and many stores are now operating their usual trading times.
It's worth noting that among the changes many supermarkets still have special hours in place for NHS staff and key workers, as well as the elderly and the vulnerable.
Asda reminded customers of this on their social media pages, outlining priority hours and asking customers not to shop during these times.
Asda is asking customers not to shop before 9am on Mondays, Wednesdays and Fridays, despite being open for business.
The supermarket previously shared the news on social media, but the information hasn't changed.
Posting on Twitter, Asda wrote: "Help us support our NHS staff, Care Home Workers & Carers by not shopping before 9am on Mondays, Wednesdays and Fridays.
"On these days we will be prioritising those key workers in our stores from 8am - 9am, so they can shop and get what they need.
"We will also be opening our stores on Sundays an hour earlier, exclusively for browsing, for these key workers.
"We ask NHS staff to please have their ID cards or registration numbers to hand and Carers or Care Workers to bring either work ID or a letter from their employer.
"We’re doing everything we can to keep our shelves stocked and our deliveries coming – so you can get what you need, whatever time of day you shop with us. Together, we can look after each other during these challenging times."
