Thank you Skyman for a balanced post, unlike a certain other who just calls people "argumentative, dismissive, immature and just plain rude" if they dare to have a contrary point of view.
I did actually compliment passport control for improving and a single queue for me works much better than a queue for each desk (everywhere) contrary to what, it would appear, research suggests.
It certainly transformed getting into BKK and my local post office.
If I want to complain about security (everywhere) it would be as much about the eejit pax who wait until they are at the machine before taking off belts, laptops out etc etc. Can't they do that while they are still in the queue??? I do (halo above head) and it is so easy.
