"there should be an IT bod in the vicinity to help explain things"
Well, the biggest reason people tend not to ask the IT folk is that far too many times when they ask, many IT folk respond with condescension and ego. An attitude that you have perfectly demonstrated in your comment (Although you do seem to have a thing for sheep).
At least this is the most common complaint that I've heard from the employees where I work ever since I fell to the Management Side of the force and got my lobotomy / MBA. Speaking with CIOs in other companies, the story isn't all that different.
