Absolutely! One of the problems with most travelers is that they don’t investigate. Even Fodors or Frommers will tell you most of the problems in travelling. One of the most astonishing things about living in NYC is encountering Brits who don’t know about our tipping practices! How can you be so stupid?
That is odd. I can’t imagine wanting to visit a country unless I knew something about it, which would include culture, customs, language, accomodations, areas to avoid, political climate and so on. The world can be a dangerous place and anyone who doesn’t realize that may well regret it.
