Is it properly internationalised?

In the workplace some places expect you to take your jacket off and roll up your sleeves. You're not working hard enough if you don't. Other countries expect you to have sleeves unrolled and tie nice and straight, otherwise you're a sloppy worker.

I can definitely see someone (but not me) paying a small amount for that kind of information - the cultural notes you need when visiting some other nation.
