SIR, Last Sunday I did a big shop in Lidl and went to pay with my credit card which was, surprisingly, declined. I asked the young woman at the checkout to put my purchases behind the counter and told her that I would return in the afternoon to pay for and collect them. I heard the man behind me in the queue ask what the bill was and was told it was £21. He pulled out a £20 and £5 note and gave them to the cashier. I protested that I was able to pay for my own purchases, but how kind it was of him to offer, but the purchase had been completed. He wished me a happy Christmas. I asked his wife for their name and address, so I could write and say thank you; but she would not give them to me. They had their daughter of about eight or nine years with them and spoke with a foreign, possibly Hungarian accent. I hope they read the Beacon or a friend shows it to them, because I want to thank them most sincerely for their great generosity and wish them a merry Christmas and a very happy new year.
