[单项选择]Promptness is important in American business, academic, and social settings. The importance of punctuality is taught to young children in school. Tardy slips and the use of bells signal to the child that punctuality and time itself are to be respected.
People who keep appointments are considered dependable. If people are late to job interviews, appointments, or classes, they are often viewed as unreliable and irresponsible. In the business world, "time is money" and companies may fine their executives for tardiness to business meetings. Of course it is not always possible to be punctual. Social and business etiquette also provides rules for late arrivals. Calling on the telephone if one is going to be more than a few minutes late for scheduled appointments is considered polite and is often expected. Keeping a date of a friend waiting beyond ten to twenty minutes is considered rode. On the other hand, arriving thirty minutes late to some parties is acceptable.
