> I expect a light switch button on a plane act like any other light switch button everywhere else
Me too, which was why I was very surprised when I discovered light switches in the USA worked backwards[0]. :D
(When I initially read your comment I didn't notice the use of "button" by which I guess you're referring to a push-button toggle style switch? But either way I still think light switches are an interesting example of non-obvious things that don't work the same way in all environments. (Even ignoring the "one light controlled by multiple switches" situation.))
