Reminds me of the time I followed a Speedbird callsign from London to Paris.
He had the archetypal plum in the mouth accent (just to satisfy the anti-BA brigade in here) and was always transferred from sector to sector at the same time as us.
On one such handover the french controller (in heavily accented English) gave him about half a dozen instructions all at once. Way too much information in one go and we expected him to muff it. There was a brief pause while he took a deep breath and then read it all back, word for word. "Bravo" said my colleague and I to each other in grudging admiration.
The shine went off it though when a few seconds later we heard [Public School Voice]"D'you know, six months ago eye wouldn't hev understood a word of thet"[/Public School Voice]
