In the past, it passed for a moment of instant fun. In shops, behind the busy payments counter, you saw this advisory on bold display: "In God we trust, others pay cash!" This was their way of telling the customer that you’d better pay for the purchase cash down, no running after in case you default! Long after those times, you are perhaps inclined to believe that the cash-only obsession has withered away. Think again!
