A work senario is totally an inappropriate comparison.
That said, if a new staff of mine keeps on asking how to do this and how to do that, I can guaranty you that this staff will not last long. It is not a newbie or senior thing. It is something to do with initiative, and the ability to learn on their own.
Back to CS, and yes, it is true this is a social enviroment and not work, but, I do often see stupid questions, follow up by more stupid questions. Stupid questions can be easily clasified as questions where the answer is obvious, readily available, and does not make sense.
Yes, one could say, we should just avoid these asker of these stupid questions, but then, why should we. OR conversely, we could say, please dont ask stupid question, or a stupid question deserves many stupid answers/responses.
