It can happen everywhere, but I don't think it is frequent. I travel fairly frequently and I've never had it happen to me, or seen it happen to anyone around me, or personally know anyone it has happened to.

It's true it happens, and you do read about it on the internet. But I think in every case I've read the person was already being questioned by immigration at a heightened level when it occurred.
