Overheard at LBA a few years ago (aircraft was, from memory, a British Midland Fokker)
ATC - XXXX Stand 5 facing West please. Pilot duly repeats instruction and heads for the stand.
Two minutes later:
ATC - XXXX, Alright then, stand 5 facing EAST!
Reply from pilot, sounding somewhat embarrassed, "Oh,... er, ... well you see we are used to facing east and anyway, we like to watch the sun come up!
