厕所，曾被美国人戏称为“实现现代化”的最后一块地方，一场风靡全美的“厕所革命”改变了人们对厕所的认识，居然也给一位有识之士提供了一个发财的机会。一天，一个叫艾佛兹的美国青年在一家餐厅的洗手间突然发觉，这里洁白的墙壁上没有任何张贴，心想，这是多么大的浪费呀 The toilet, the last place that Americans jokingly called “realization of modernization”, was a nationwide “toilet revolution” that changed people’s understanding of toilets and provided an insightful opportunity for a man of insight. One day, a young American named Evers was suddenly found in the bathroom of a restaurant. There was no post on the white walls. I thought, how wasteful this is.
