An hour and a half to get through passport control and a very rude surly customs officer who was shouting "move move" at people in line. He then barked at me and refused to handle my declaration form after it briefly touched my lips - he told me it was now germy. This was despite posters saying that customs and immigration officials would treat people with respect.
