Is it my imagination or has there been an increasing trend for some time now for any kind of business to give you a receipt for the tiniest thing? Even in pubs!!! I realised it when I bought something from a branch of Dixon's in the UK. I politely declined the receipt and the girl on the till said that I had to take it. "No I don't", I replied. "But it's policy that every customer has to have one." she said and was beginning to look stressed. I felt a bit sorry for her and said, "Well if the manager whinges, just tell him it's not my policy to take them." And so I got out of the shop receiptless. What is behind this receipt mania?
