What is your favorite color? Do you like yellow, orange, or red? If you do, you must be an active person who enjoys life. Do you like blue? Then you are probably quiet, shy, and would rather follow than lead.

Colors do influence our moods (情绪). A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(令人压抑的). There was a black bridge over the Thames River, near London. The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green.

Light and bright colors make people not only happier but also more active. In the factory, the workers will work better, harder, and have fewer accidents when their machines are painted orange rather than black.

王某在某机票代理处购买四天后起飞的打折机票一张。第二天,由于特殊原因,王某向该机票代理处提出退票申请。机票代理处虽然同意退票,但告知王某打折机票的退票费需按机票原价的50%扣除,王某对此提出异议。日后,王某又与承运人某航空公司交涉。航空公司认为,本承运合同的当事人应是王某与机票代理处,自己不存在违约问题,尽管机票上印有退票条款,但退票费的收取应按航空行政管理部门有关内部文件的规定执行。王某认为,航空公司的行为违反了诚信原则,并且未尽告知义务,已构成违约。在协商未果的情况下,王某向法院提起诉讼,要求航空公司及代理处返还扣除的退票费。
相关背景资料:
(1)机票上有关退票的规定:旅客在客票上列明的航班规定离站时间24小时以前要求退票的,退票手续费由承运人规定;在航班规定离站时间24小时以内至2小时以前要求退票的,收取客票价10%的退票费。
(2)航空行政管理部门有关“打折机票收取50%的退票费”的规定,未曾正式向外公告,只是在管理部门指定的航机读物,即行业报纸上以新闻形式出现。
(3)机票上有关退票的规定是执行航空旅客货物运输规则中的相关规定。
(4)航空行政管理部门有关打折机票退票费的文件实施时间,晚于航空旅客货物运输规则的实施时间。
(5)对机票上“退票手续费由承运人规定”的条文,航空公司没有证据证明原告已经知道。
