Re: The wish thread.
A little googling reveals that it has something to do with Indian language - and that it's EXTREMELY ambiguous. Seems to mean 'yes,' 'no,' 'I agree,' 'you're a twat,' and a whole host of other things. So most likely if you encounter a person who learned the language from a native Indian (as it seems to be contagious) they will wiggle their heads when they talk. I've yet to come across an explanation of why they do it in the specific context of talking to a salesman (i.e. me), so I'll have to do some constructive observation of the local Indian populace and get back to you folks if I have any epiphanies.
