Having worked on several continents, I know how difficult it can be to adjust to different cultures.
In Poland, for example, men kiss men at work. In the United States, on the other hand, they sue for that kind of thing.
So you have to feel for any American who is suddenly asked very nicely by his employer to leave the deep safety of the nation and venture to, say, the United Kingdom.
They're different there. They're tight-lipped and generally superior.
Kinder employers, therefore, create little handbooks to prepare unwitting expats for a new world.
