I think it may be better to give some good advice to anyone asking what may appear to be a rookie question.
"Try to come up with 3 solutions to this problem. 3 good solutions. Then determine which of them is better in this case. Could be the design dictates it, or the costs, or more." This exercise will help teach the guy the fundamentals that will serve him down the road.
Sort of like the old "Feed a woodworker a fish, vs teaching him how to make a fishing pole so he can feed himself".
Also, if the poor guy can not come up with 3 ways to skin the cat, or catch a fish for himself or the cat, or scribe cabinets, then he may get the idea that he is better suited for another line of work.
I might add that I spent 26 years as a professional woodworker before I ever had to scribe a cabinet to fit between two walls. Mostly building curved stairs. I asked around a bit, but did not much care for their ideas (The best was "carefully pound the drywall until it is pulverized without breaking the paper, then push the cabinet in place). I figured it out, and still use that method most of the time 20 years later, on the rare occasions we need to do it.
