I suspect that the chap you heard had assumed he had been cleared to cut the corner of the zone.
The chap in the helo actually did say that and the response wasn't very friendly!
2Donkeys, squibbler and Warped Factor are completely correct in what they are saying as was the Senior ATCO afterwards, it was a) the fact he decided to comment after the previous ATCO had cleared up the matter and b) the ferocity of his attitude that made me take notice of the exchange.
IO540 I assume that they do tend to watch that corner of the Zone as there are two strips, three airfields and an airport within 30 miles of it
