在阿尔布雷希特兄弟小时候,他们的母亲经营一家杂货店,店里也卖信封和邮票。当时邮票是不赚钱的,从邮局按票值进,然后以同样的价格卖出。而卖出一个信封,所赚的利润也微乎其微。令兄弟俩不解的是,母亲还为顾客提供胶水粘邮票和信封,提供桌椅和笔让顾客填写信封。当时,卖出500个信封所赚的利润才能买到一瓶胶水。算下来,卖信封不仅赚不到钱,甚至赔钱,但母亲却坚持这样做。 In the days of the brothers of Albrecht, their mother ran a grocery store and the shop sells envelopes and stamps. Stamps were not profitable at the time, and were sold at the same price from the post office. And selling an envelope, the profits made are minimal. What puzzled the brothers was that the mother also provided glued sticky stamps and envelopes for customers, provided tables, chairs, and pens for customers to fill in envelopes. At that time, a profit of selling 500 envelopes in order to buy a bottle of glue. Counting down, selling envelopes not only make money, or even lose money, but my mother insisted on doing so.
