Tesco has been pulled up for yet another supermarket blunder after a customer spotted a rival's product on one of its shelves.
The grocer - Britain's biggest - has been caught out after a shopper spotted a rogue bottle of fruit juice from Sainsbury's hidden in its beverages aisle.
The error was first spotted by Demi Boonham, who posted a picture of the awkward item in a popular bargain hunters' Facebook group.
It shows an own-brand bottle of Sainsbury's fruit juice tucked behind dozens of Tesco bottles at a Tesco store in Lichfield, Staffordshire.
Speaking exclusively to our sister title Manchester Evening News, Demi explained how she had taken the picture after being left stunned.
The post has since gone viral, and has racked up more than 100 comments and over 500 likes, with other shoppers also entertained.
Writing under the post, one amused customer said: "Can't wait to show my husband this, he swears he only likes the Tesco brand, brilliant haha."
Another customer joked: "It took me way too long to see what was wrong in this picture."
"Awww. The poor lonely Sainsbury's bottle," commented somebody else.
While it may be a shock to spot a rival's product on a supermarket shelf, it's not as uncommon an occurrence as you may think.
Back in September, Aldi shopper Charly Arnold was happily making her way through a multi-pack of Snackrite ready salted hoops when something strange happened.
She looked down at the familiar red and yellow packet and realised that it didn't say 'Snackrite' at the top.
It said 'Hula Hoop'.
She posted a picture of the bag online and wrote: "Just took two bags of 'proper' Hula Hoops out of the Aldi Snackrite multipack.
"Just goes to show how people are only paying for a brand name with most things," she wrote.
Many supermarket own-brand products are manufactured in the same factories, and while efforts are made to keep them separate, errors do happen.
The good news, however, is that in the case of Sainsbury's and Tesco, both bottles cost the same price, at £1 each.
The only difference is that Tesco's version has a five-star rating online - compared to the four star rating at Sainsbury's.
A Tesco spokesman said: "Everyone is welcome at Tesco, so we’re pleased to see that this particular bottle has good taste, making its way to our shelves to celebrate 100 years of great value with us."
