If you're a traveller looking for something that takes a richer and more longitudinal approach; a business person or civil servant looking for insight beyond the usual Dos, Don'ts, honorifics, platitudes and rituals; a student of the humanities and social sciences wanting something more grounded in the world today; or a seasoned dinner party socialite and pub quiz pro looking for a global Zeitgeist to boost your social capital - then this is definitely the book for you. There's plenty to learn, it sinks in easily, and this is the sort of book that you'll find yourself marking-up and folding page corners on.
