I loved reading this. Everything you described was so typical! I've been to that airport countless times. It has modernized a lot over the years. I'm surprised you still had to hop on the shuttle bus. That is common but I thought they were building or had already finished the gate/s to disembark directly into the building. I wonder when the hotel they are building will be finished.

The system for customs inspection is also funny: just an RNG button that either flashes a red or green light.

I've heard many superstitious people claim that the button senses your nerves or sweat on your hand or intuitively knows that you are hiding something in some way. Hilarious.

The sitting and waiting until the mad scramble to the exits is over was also a strategy I remember my grandpa using when we would fly together.

P.S. Even the street cops are fully decked out in military-like vests, helmets, and automatic rifles.
