Hehe, I was all smiling reading this. Your experiences on how humans have been themselves demonstrated while at the airport is fun!
I haven't been to the airport, but I have been to the train station and ... I have the same feeling while there. The last trip I made last year was so not fun but was later funny. Hehe.
They changed the setting of payment, and it wasn't fun because I had to run around to ask for someone to help. It was very frustrating, but I was able to check in and find my seat number. Hehe.
Here's a picture of the train I took some months ago. It isn't very clear because of the phone I used then.
Train stations can be similar, have a similar feel, to airports...more the large ones that distribute people to other countries like in the UK and Europe I guess. Wherever humanity comes together there's usually something interesting to see, an interesting person to meet...and the complete opposite too I guess...(not interesting people.)
Lol... haha, the last statement was a banger. And, yes, wherever people are gathered comes lots of drama. Hehe.
