"without losing face"? What culture are you referring to? The Western companies I have worked at do not discourage such questions -- in fact, it's often the sign of someone very senior when they ask a seemingly 'dumb' question that others have taken for granted.
Company culture. Some companies I worked for would fire you for questioning decisions. Others, welcomed criticism. You don’t really know which environment you’re in until someone says something. Are you going to take the risk and be the first?
Absolutely. If the company I work for happens to be one that's so crappy that I'd get fired for questioning things, it's better to find that out as soon as possible. That's not a company that's worth my time and attention.
