So we must smile and politely serve the customer, anyway that we can, to make customer confidence with our service but there are a lot of characteristic in which the cabin crews must have for make customer satisfaction and delight. When you can make a good service mind, you must need to conduct all of these to the customer. For sure, every national in the world can understand the body language but it is untouchable. The language will fix this problem where you can translate your service into the touchable things.
