假设有人走进一家时尚男装店,说自己想买一套西服和一件毛衣。如果你是售货员,你该先给他看哪样东西,好让他花最多的钱呢?服装店指点销售人员,要先给顾客看贵的东西。依照人们的常识,顺序应该反过来才对:要是人们买西服时就花了大把的钱,他恐怕不愿再多花钱买毛衣了。 Suppose someone walks into a fashion menswear store and says they want to buy a suit and a sweater. If you are a sales clerk, you should give him a look at what kind of things, so that he spent the most money? Clothing store pointing salespeople, to give customers first look expensive things. According to people’s common sense, the order should be reversed: If people spend a lot of money when buying suits, he probably will not want to spend more on sweaters.
