Some years back, i bought a pair of Brogues from M&S for £43. I worked 6 days behind a bar at the time and wore the shoes on Sat and Sun. I was dressed more casually the rest of the week. I never EVER keep receipts, but on this occasion, i tucked the receipt in the little pocket of my wallet, which was just as well. Taking the shoes off just the 3rd weekend of wear, i saw that both soles had splits right across their width. Obviously took them back and asked for my money back. CS went 'upstairs' (literally to a higher authority) , returned and said that they look 'well worn'. I produced the receipt, which proved i hadn't had them long enough for them to be 'well worn'. I also informed her that i only wore them behind the bar at the weekends. She went back upstairs, returned and informed me that, this time (!) they would refund me. She explained that the splits were probably caused by "all that bending down". I was tempted to ask her "What bending down?" Instead i pocketed the refund, left the store and have never bought any item of clothing from them since.
