Things An Air Hostess Won't Tell You To make things a bit easier for them and ensure a smooth flight, many Flight attendants have little tricks under their sleeves. Here are some of them which they won't tell you out of sheer politeness. 小题1:__________ Contrary to what most people think, a flight attendant's primary job is to ensure your safety - the helping and serving part of their job are just add-ons. If they are assisting you with your luggage, it is to make sure it is stored properly and does not harm anyone. They are not required to lift your bags or help you take them elsewhere. All the other assistance, such as providing you with a drink, handing you hot towels, etc., are to make sure you stay calm and satisfied. 小题2:__________ As unfair as it may seem, the time that a flight attendant spends in getting the plane ready, settling you down, etc., is not included in their salary. They do, however, receive some expense allowance(津贴) for the entire time they clock in - it is a pretty small income though 小题3:__________ If a flight attendant feels a passenger is ordering too many drinks, and getting drunk, they might avoid serving him/her by avoiding eye contact. When that fails, they might just fill the glass half-way or give him/her a diluted (稀释的) drink 小题4:__________ A number of training programs and workshops exist to train flight attendants in different aspects. As some people are using flights more and more to smuggle (走私), flight attendants are being regarded as the first line of defense against this heinous （邪恶的）crime. The benefits are already evident - a number of dangers are avoided, thanks to alert(警惕的) flight attendants on board 小题5:__________ This is a bit unfortunate for those sitting at the back of the plane, but nevertheless true. As the attendants start serving from the front of the plane to the back, the variety of drinks or meals might go down. This is because a plane has limited space, only a certain number of items can be stored, and by the time they get to the back of the plane, they run out of at least a few of the options.
