I think your measure of what is ok and what isn't is just on the basis of what you are comfortable with. Doesn't mean every other programmer is comfortable with the same.

To tell you the truth, I am ok with coding questions. In fact, I demand it. What I'm not ok with is demanding inch-perfect code in 20 mins. The only people who can be perfect are the ones who are doing the exact same problems everyday....not the ones who are doing production work.
