MD, this time I have to disagree with you. You have to respect the rules of the place where you live, work, and spend your holiday. Some places are more open, some places are more strict, but obviously all of them have their own rules.
I would say, etiquette guide is a good move, as people who come to visit this country have to know about certain restrictions and not to get into trap of their own unawareness…
and again, I don't think having sex in public place would welcomed even in Canada or somewhere in Holland after having couple of 'cigarettes'
