geez people!!
Ok - more than once have I had to ring up a pilot and apologise for something that ATC did/didn't do. If something didn't happen they way you want it to, stop whinging and pick up the phone and speak to the supervisor. I don't know just how busy you are after a flight, what with debriefing and bars to get to, but surely you can have a reasonable discussion on a phone. If you aren't happy with the supervisor, ring the Flight Commander or SATCO. For those that can't be bothered doing that, submit paperwork to your management and they will chase it up for you. Personally I think that in most instances that is the pissy way to do it, but its up to you. If you really want to find out whats going on, instead of racing to the hotel, go and visit the section.
