1-- May I help you?
 
2-- Yes, please. Could you tell me something about going through customs?
 
1-- Certainly. What would you like to know? Please go ahead.
 
2-- Thank you. What formalities do we passengers need to go through at the airport?
 
1-- There are some, but not many. They won't take you a lot of time.
 
2-- OK, that will be fine.
 
1-- Firstly you have to answer some questions from the officers.
 
2-- Like what?
 
1-- Your purpose of visiting, how long you will be staying, things like that.
 
2-- Well, that's easy.
 
1-- If you have brought something which has to be declared or something dutiable, you have to declare and pay duty on them first.
 
2-- I get it. Thank you so much.
 
1-- You're quite welcome.
