Apologies RetiredBA I admit I did bite a bit too hard. Maybe its because I was in during the 80's at the height of the cold war.
There was very much an attitude of 'Don't tell them Pike' about all things green.
I acknowledge that at a presentation given by the CAS there are not going to be secrets disclosed.
I think it was the mention of a bar where your conversation took place that tweaked my old, still ingrained reflex action.
Put it down to watching all those old 'Who is listening' films we had to watch.
