Welcome to AMD jail - as you go through boarding or deplaning you are treated like third world citizen - there are so so many security guards at every levels & every 50 feet.
They will check your ticket / passport / papers so many times that you will get sick - but the irony is - many of them are uneducated & stupid(beyond your imagination) & many do not know how to read English and do not know what are they looking for. They exist because there is a corrupt organization behind hiring these people.
I hope some local reporters investigate the custom and security people. There is a criminal ring at work. I do not know at how many levels. But hey this is India - we are corrupt to the bone and like it and proud of it and will stay corrupt till you die.
