If you're not caught flouting their laws or being rude then, in my experience, they're all fine. The US is the most intrusive - fingerprints and photo every time you enter, but it's only a problem if you find it a problem (if you see what I mean).

What probably didn't help this lady is that she was being really quite rude. I don't know any country where low level officials take kindly to that. You REALLY don't want to be rude to US border agents. I mean, they have signs that say not to make jokes as they won't take kindly to that sort of behaviour.

For some reason my spellchecker thinks I've spelt behaviour incorrectly (and spelt). How colonial.
