Lets not fool ourselves here.
No one in the GC tower is going to loose any sleep over the opinion of an incompetent **** from the flying school are they.
Everyone knows that the GC tower guys are very professional and top blokes.
The supervisor with whom you have lodged your complaint will be having as big a laugh at you as the rest of us.
You have once again proven you are a fool.
Go slap a few more gold bars on your shoulder, see if that makes you feel any bigger.
