Airports are strange and liminal places where the perception of time itself starts to break down. Flying long-haul is the only time you can somehow eat five meals in the same 'day', and airport bars are the only places that serve beer at 7AM and nobody thinks anything of it, because 7AM to one person might feel like 7 at night to the guy waiting for his layover from Singapore. It's weird but kinda fascinating.

The only thing I dislike is that the food is expensive and disappointing.

You’re not alone, I feel the same way. I love the act of traveling almost as much as getting to my destination. I really like your quest description! I always look at it like a game. Figuring out the secret ways in the airport, gaming the system.

Agreed, but it is also loud and busy.
