Travelling to every part of the world is getting easier, but how well do we know and understand each other? Here's a simple test. Imagine you are planning to hold a meeting at four o'clock. What time should you expect your foreign business friends to arrive? If they are Germans, they'll arrive on time. If they are Americans, they'll probably be 15 minutes early. If they are Englishmen, they'll be 15 minutes late. You should allow up to an hour for the Italians.
