Everyone hates to wait in lines. But our behavior when waiting is only partly defined

Everyone hates to wait in lines. But our behavior when waiting is only partly defined by the length of the wait. “Often the psychology of queuing is more important than the statistics of the wait itself，” notes the MIT researcher Richard Larson, an expert on waiting lines.
Some people are (41)  to camp outside Apple stores for an entire night just to   get their hands on the latest product. But waiting 10 minutes in a grocery store just to buy a drink? Forget it.
One apparent aspect of queuing psychology is that we get (42) when we wait in line. This issue is tackled ( 处 理 ）in many ways, from magazines in hospital waiting rooms to mirrors in elevators so that we can check our (43)        . But we really hate it when we expect a short wait and
then get a(n) (44)  one. But studies show that we are much more patient when we are given a(n)
(45)  of how long we'll be waiting.
Scientists have invited 200 people to do a simple experiment. While a group of 100 people are given an exact time of waiting, another group people are left (46) . It turns out that more people from the first group than the second one refuse to (47)        .
Walt Disney Co. knows this better than anyone else. It (48)        waiting times for attractions in its theme parks. But according to Larson, these times are overestimated so that visitors get to the front of the queue more (49)          than they expect. It keeps them happy.
Another big influence on our feelings about waiting in a line has to do with our perception of fairness. When it comes to queues, the universally acknowledged    (50) _ is first come，first served. Any deviation (背离)from this is regarded as (51)  and can lead to violent queue rage.
Sometimes, however, we are willing to make (52)      . In hospitals，(53)       ，priority ( 优先权）is given to those with a more critical condition—we can also understand that.
Waiting is inevitable in life, but a better understanding of the (54)   of waiting can help   make it a bit more bearable. When all else fails, bring a book or a smartphone will also (55)        .
