I was being more facetious than factual, but I have had experience with it first hand also.
If the job has gotten to the point where the BO has to leave his office and check on it, you as the contractor had better have done everything right, because what you are saying is that one of his trained staff (deputies) doesn't know his job. On the other had as the inspector you had better be able to back up your call with a code section.
Now for just a little more clarification and not all departments are set up the same, but by the time you have gotten to my BO, you have gone over the head of my supervisor and my deputy BO.
One of the times it happened and I was correct, I was told by the BO that the contractor wanted to make sure that he got a "by the book inspection" as he winked at me. That, is a very thourough and long inspection, that book is really thick.
