Americans have a strong sense of time. They cherish time very much and don't like others to "waste" time at the same time. In order to squeeze out more time, they always do things quickly, walk quickly, eat quickly and buy things quickly. So fast food is very popular in America. In order to improve work efficiency, they usually communicate with others by phone or email and get to the point, but in China, we prefer to talk in a relaxed environment, such as exchanging pleasantries while drinking tea. In America, if you can finish a job quickly, you will be regarded as an efficient and excellent worker. Of course, China agrees with this.
