Squish my Butt

Rode the train to work again today. Seems one can observe more human interactions than when tooling down the highway in my car....

At the station Hermannstr. I saw a young couple leaning against a wall, each with a heavy-looking suitcase. He was Turkish-looking, smoking (which is forbidden, but who respects that); she was German-looking, not smoking.

He finished his cig, flicked the butt away. He got her attention, pointed to the butt. She obediently stepped on the butt, squishing out the fire.

It would have been trivial for him to do this himself. As the train pulled out of the station I wondered why she would do something like this for him and why he would expect it.
