Kissing a lady's hand

The extinct social rituals thread reminded me of this.

I was reading a travel story and the author remarked that Poland is the only place where men still kiss a lady’s hand. That surprised me. I didn’t know this custom was dead elsewhere. I never really noticed it, but when I think about it the only times I can remember doing it myself I was either in Poland or at a Polish gathering. In North America you only see it in old black and white movies.

Has it just become uncommon or did I just miss the obvious?
