Can't speak for my colleagues but if you sound like an idiot and/or act like an idiot and/or I have good reason to believe that you are an idiot then I might tell you to avoid controlled airspace unless I have cleared you otherwise.
It takes 2 seconds max and it is worth it to reduce any liability that I or my employer might have in the event that you cock up on my watch.
I of course expect to be called many things for saying such nasty and offensive words as this. But I don't care.
