No matter how many times you try to remember, one of the most gruelling parts of going to the supermarket can be searching for change to use a trolley.
Of course, not any change will do - you need to have a £1 coin handy. But sometimes, when you need it the most, you just don't have one on you.
However, a supermarket shopper has shared a clever tip on unlocking trolleys without a £1 coin - and it's amazed people. Taking to short-video platform TikTok to share her satisfying tip, Tasha's video has surpassed 1.4 million views since posting.
