The story on the BBC site concerns people who attempted to pay with their chip card by placing it in the reader but had their contactless card charged instead, which was still in their purse/wallet. In some instances, the transaction was processed twice using both forms of payment. The first customer was able to obtain a refund after demonstrating the problem to the store manager.
