Tesco has introduced stricter security measures in one of its Essex branches, including attaching security tags to shopping baskets and limiting customer entry at certain times. The decision was made in response to an increase in local thefts, with management stating that the tags serve as a reminder for customers to return their baskets. While some shoppers have expressed skepticism about the effectiveness of these measures, Tesco emphasizes that the store-level decision is part of a wider effort to ensure the safety of staff and customers.
