The Dubai international airport probably on of the best in the world.The airports entrance is magnificent and clear inlets of departure for passengers without any traffic blockage as in the case of Sharjah international airport where a single car pooling would block the entire area in a given manner.After the entrance through the Glass slide doors you have state of the art chandeliers hanging and making the entrance even more exotic.Then you will meet the rude cops of Dubai which when it comes to cops the whole of cops in the U.A.E are of the same attitude.The females except at the body scan arena are all sweet conversationalist.The staff probably in general is rude that is wherever there is a security checkup in U.A.E so misguiding them is an uneducated thought.
At the immigration talk only what is asked because if you talk more tham asked then you would never know what situation you have just integrated.
the only problem is walking long ways along the airport.But at least they have walking escalators so you can reduce the leg pain in a considerable manner.Then comes the next round of checking.Then you have the large arena for the different boarding sections in a systematic manner.The duty free is the place where you can pop in any type of edibles and drinks you want especially the chocolate ferreo and twix quality street and many others also you can buy some good whiskey or scotch of your choice.
The only way to carry yourself smoothly throughout airport is that you have to oblige to the commands of the officers and staff or else you will be called aside for minor grade interrogation or in the lesser form of argument with you that show me your passport and unnecessary questions of what business do you do and no matter what you answer you will not be heard or accepted by them.Never try to talk and try to make friendships with any girls in Burkha especially Arabs because you are just inviting more trouble to your current scenario.
