I seem to be one of the few people who actually enjoy my time in an airport...

It is fun to watch the planes come and go, to see people heading all over the world, it is interesting to see destinations all over, also, in larger airports, the architecture can be quite interesting.

I also like the feeling of being on a video game quest, you have a single main quest, to get on the plane, but you may have several side quests, getting snacks, eating, getting a powerbank, getting some tax free stuff.
