Passage Two

　　Questions 16 to 20 are based on the following passage:

　　While catering generally received high marks from most of the cabin attendants responding，there were a number of highly critical comments.

　　Cost and packaging are generally still big issues. A catering order for breakfast and lunch for six，excluding expensive wines and imported items，can usually be a little too high for the passengers.

　　One cabin attendant listed as frequent problems spoiled and out of date dairy products，incorrect orders and late deliveries. And she added，With the prices charged by caterers in major metropolitan section，it isn’t unreasonable to expect an order to be complete，exact，fresh and of the highest quality and on time.

　　One caterer has “beautiful and delicious food，” but the packaging isn’t flight attendant friendly because they package hot and cold items together，as well as hot items together that require different heating or cooking times. Then cabin attendants have to go through the entire order and repackage it before the passengers get aboard. This happens regardless of the order request.

　　Other specific complaints included: store-bought cookies passed off as homemade and failure to make use of the Internet for placing and confirming orders.

　　In conclusion，the survey suggests that while cabin attendants are generally satisfied with the overall performance of business aviation caterers，although there are unforgiving of mistakes. And they are almost unanimous in pointing out that it takes only one mistake to ruin a flight or lose their job.

　　Catering is critical，getting the order right and getting it to the airplane on time is key. The most difficult part of a meal service is the preparation. Actually serving the meal is simple by comparison.
