Colour London

We saw a cap, priced at £10, on a shelf with all items priced at £10. We bought just a cap, a mug and some magnets. The total came to £67. We paid and then checked the bill: there was an item priced at £40. We asked what it was. The salesperson told us “it was the cap”. So we told him “it is marked £10, so we told him we don;t want it if it is £40 and asked for refund” he refused to refund us although we were still in the shop and had not even left yet. He told us “no refund”. Bunch of thieves, avoud at all costs. I will report them to the tourism police. They make London and the UK look bad.
