When I first became a manager, I had this really amazing mentor that explained to me a lot of the quirks of multiculturalism. I consider myself at least somewhat versed in other cultures, but I quickly learned there was a lot I didn't know about the mannerisms of people from India, China, Russia, etc.

What I find sad, is that there are a lot of people in positions of power that either have no idea (or don't care) that people from different parts of the world see things and respond differently than you'd expect and then get frustrated when the outcome is different than expected. I'd explain to them that it's a cultural thing, and they need to learn how to approach their questions/explanations differently. Most of the time I get this blank look like, "Why? Can't they just change?" and then go back to trying the same approach and calling their staff down, because they can't seem to understand why they are ineffective.
