You know what?

在美国的餐厅吃饭，如果有侍者为你服务，来向你要点什么菜，这种情况是要付小费的。但如果是在快餐店，如麦当劳，自己点餐到座位上去吃，这种情况无须给小费。一般情况下，午餐要付10%-15%的小费，晚餐则付15%-20%的水费。付小费有两种方式：一种是把现金直接留在桌上，注意最好不要都是硬币，至少有一张纸钞。另一种是用信用卡付小费，在账单上签小费的数目及总和。

The Missing Dollar 不翼而飞的一美元

Three friends have a meal in a restaurant and they are charged $25. They each chip in with a $10 bill and hand it to the waiter. The waiter, though, isn’t very good at math, so he keeps $2 as a tip and hands each friend $1.
Everyone seems pretty happy with the deal until one of the friends starts thinking about it. The three of them paid $10 each but got $1 back, so that meant that they spent $9 each. And since there were three of them, the total was 3*$9, or 27, plus the $2 tip for the waiter. That takes the total to $29. But they gave the waiter $30.
What happened to the missing dollar?

三个好朋友在一家餐厅吃饭，他们一共消费了25美元。每个人出了10美元，并且把钱递给服务员。然而，这个服务员不太擅长算数，所以他收了2美元作为小费，并且给了每人1美元。
大家这顿饭吃的似乎都很高兴，直到有一个人开始想到：三个人每人付了10美元，但就找了1美元零钱，也就是说他们这餐饭每人花费了9美元。因为是三个人，总共消费了27美元，再加上服务员的2美员小费，所以这顿饭总共花费了29美元。但他们给了服务员30美元。
剩余的一美元哪去了？
