Tesco often changes and updates its products to meet customer demands. Since the beginning of the pandemic, the supermarket has also made changes to its stores, putting additional features in place to make it easier for customers to shop safely and efficiently.
The barriers are being trialled in the Tesco Extra store in Sutton Coldfield, Birmingham.
But if successful, they could be introduced to more stores nationwide.
The security doors can be set to open automatically as customers approach the alcohol aisle, or they can be open with a key card by a member of staff.
This means all shoppers would be supervised when buying booze.
The barriers have been put up because shoplifting has become a problem for Tesco in recent months.
Thieves are taking advantage of the supermarket’s lack of staff during evening and night shifts when stores are quieter.
A supermarket source said: “It is quite an extreme method to cut down on theft but a very effective one.
“They are a bleak sign of the times but will save Tesco a fortune.”
Express.co.uk has approached Tesco for a comment on the move.
It comes at the same time as another Tesco Extra store, located in Rotherham, has started to check customer receipts as shoppers exit the store.
Tesco placed a notice near the Rotherham branch’s doors, saying its staff are “continually looking for ways to make your shopping trip as simple, safe, and pleasant as can be”.
It added that employees will be “asking all customers to produce their receipt for goods purchased when leaving the store”.
The notice continued: “We know this may sound a little unusual, but we genuinely believe this is the right thing to do for our regular customers.
“We’ve listened to lots of customer feedback over the last six months and the biggest thing people speak about is wanting to feel safer in the area and our store. We want this too!”
This initiative has also been put in place due to decrease thefts in the store.
In other Tesco news, the supermarket has recalled its own brand Max All-In-One Chesty Cough & Cold Lemon Sachets due to incorrect labelling.
The medicine should not be given to those under the age of 16, but some of the sachets being recalled say children aged 12 and over can take them.
Around 78,000 packs are affected and are being withdrawn from shelves.
