Business culture: formality to your managers
In where you're from, if you want to maintain a good relationship with your boss or CEO of your company, which is more important, being polite to them or being friendly to them?
For example, when you talk to them, do you talk to them casually or formally? Can you say to them "can you open the window?" Or, do you say "would you open the window, please?" Or, you don't ask them for such a favor because you think it's rude?
