In America alone, tipping is now a ＄16 billion-a-year industry. Consumers acting rationally ought not to pay more than they have to for a given service. Tips should not exist. So why do they？ The conventional wisdom is that tips both reward the efforts of good service and reduce uncomfortable feelings of inequality. The better the service, the bigger the tip.
Such explanations no doubt explain the purported origin of tipping—in the 16th century, boxes in English taverns carried the phrase "To Insure Promptitude" (later just "TIP"). But according to new research from Cornell University, tipping no longer serves any useful function.
The paper analyses data from 2,547 groups dining at 20 different restaurants. The correlation between larger tips and better service was very weak: only a tiny part of the variability in the size of the tip had anything to do with the quality of service. Customers who rated a meal as "excellent" still tipped anywhere between 8% and 37% of the meal price.
Tipping is better explained by culture than by economics. In America, the custom has become institutionalized: it is regarded as part of the accepted cost of a service. In a New York restaurant, failing to tip at least 15% could well mean abuse from the waiter. Hairdressers can expect to get 15-20%, the man who delivers your groceries ＄2. In Europe, tipping is less common; in many restaurants, discretionary tipping is being replaced by a standard service charge. In many Asian countries, tipping has never really caught on at all.
How to account for these national differences？ Look no further than psychology. According to Michael Lynn, the Cornell paper's co-author, countries in which people are more extrovert, sociable or neurotic tend to tip more. Tipping relieves anxiety about being served by strangers. And, says Mr. Lynn, "In America, where people are outgoing and expressive, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off." Icelanders, by contrast, do not usually tip—a measure of their introversion, no doubt.
While such explanations may be crude, the hard truth seems to be that tipping does not work. It does not benefit the customer. Nor, in the case of restaurants, does it actually stimulate the waiter, or help the restaurant manager to monitor and assess his staff. Service people should "just be paid a decent wage" which may actually make economic sense.

Marriage takes some kind of sacrifice, not dreadful self-sacrifice of the soul, but some level of compromise. Some of one' s fantasies, some of one' s legitimate desires have to be given up for the value of the marriage itself. "While all marital partners feel shackled(受束缚) at times, it is they who really choose to make the marital ties into confining chains or supporting bonds", says Dr. Whitaker. Marriage requires sexual, financial and emotional discipline. A man and a woman cannot follow every impulse, cannot allow himself or herself to stop growing or changing.
A divorce is not an evil act. Sometimes it provides salvation(拯救)for people who have grown hopelessly apart or were frozen in patterns of pain or mutual unhappiness. Divorce can be like the first cut of the surgeon' s knife, a step toward new health and a good life. On the other hand, if the partners can stay past the breaking up of the romantic myths into the development of real love and intimacy, they have achieved a work as amazing as the greatest cathedrals(教堂)of the world. Marriages that do not fail but improve, that persist despite imperfections, are not only rare these days but offer a wondrous shelter in which the face of our mutual humanity can safely show itself.
