The other day I buy a pair of leather shoes in a shoe shop. The seller told me he would give “three guarantees” for the shoes. And only four days later, the shoes worn out. So I was angry and returned to the shop hoped to get my money back. I told the seller what had been happened to the shoes. When she knew that I had kept the shoes for four days, he refused, to which I was surprised. I asked him why he didn’t keep his promises. “Do you understand the ‘three guarantees’?” the seller said. “It means the shoes can only be kept in three days!” How a foolish explanation of the “three guarantees”!
