Between Shed and Roverman we appear to have two people who have actual experience of either, or indeed maybe both, ATC or airport operations. I believe that their firsthand knowledge may far outweigh many, but not all, of the other posters.
There are always two sides to an agreement, however to be rude and possibly derogatory about a person's views is to not understand, or even consider, the possible reasons for their posts and thus give a reasoned response.
