I remember one evening recovery in one of Aunt Betty's finest, having to charge through the London TCA at all the wrong time - rush hour. The London controller was doing a magnificent job, very slick at moving people the way they wanted to go - including us, cutting right across the flow.
Until a UK charter pratt tried to force his way through the carefully orchestrated scenario. After suffering the pillock for about half a dozen sarcastic calls, she very quietly reminded the captain that all transmissions were recorded, that this particular tape would be pulled for investigation because clearly she was doing an unsatisfactory job and that should the investigation find that she was following the correct procedures, he would be the subject of a violation report.
Every transmission [including my own] signed off with words to the effect that she had done a first rate job and we would be willing to be witnesses at the investigation.
Pratt said virtually nothing for the rest of his transit...
