It does seem when one asks for comment there is a degree of paranoia creeps in. I try and be as co-operative as possible with controllers and even if a service is not offered or I dont require one I try and ensure a controller is aware of my intentions, route etc. if it is required. I was just asking the reason. As for being at 2400, I was there to avoid other traffic and rather than decend I chose to go up to maximise ADF and VOR signals being used at the time. It is a partnership out there NOT them and us and both sides are guilty of getting it wrong sometimes.
