Transoceanic and Intercontinental flights, together
with tempting air fares and tour packages created
a breed of worldly American travelers. What used to
be foreign is becoming increasingly familiar. Yet
rare is the experienced traveller who has not
committed at least one cultural gaffe simply by not
knowing the acceptable or expected behaviour in
another country. Cross-cultural blunders, as
awkward and embarrassing as they can be are
hard to avoid, and most hosts understand that. But
it's always a good idea to do some homework on
foreign cultures before your trip.
