I've been dealing with BT to sort out a billing problem. When you phone it's a lottery whether you get the UK or India. The Indian staff were extremely polite, extremely friendly and totally effin useless - politely telling me that I was mistaken, that I couldn't speak to a supervisor and that the computer was infallible. That's an hour of my time I won't get back.
The UK staff are reasonably polite, not too friendly and sorted the problem out in five minutes.
Is it to do with not losing face?
