About 3 years ago on my back from Belgium to Cranfield I talked with Staplford. When passed over their zone (2400’) I called and said that I change to Luton. The young guy instructed me to call Stanstead so I replied that I call Luton. He became very aggressive and demanded me to call Stanstead. My wife could not believe that I remained calm. I told her that he might know something that I don’t and that there might be a good reason for this. Well…. there wasn’t.
