Perhaps it's an issue of clarity of RT being relative to speed. At 7-8 miles per min 250 ft, you don't have the time or brain power to waffle!
I remember flying through Spade a while back & trying to check in with ATC only to find a C130 (none RAF) on the freq, waffling on about Hadrian's Wall being a fantastic sight & a monument of Roman engineering. He then went on to ask ATC whether there were any other decent sights of historical interest! No prizes for guessing where the pilot was from.
