I refer to the letter Immigration officers may not have known English . I would like to ask the writer whether he or she has heard of something known as 'body language'.
I'm a very frequent traveller and I can assure you that compared to some of their foreign counterparts, Malaysian immigration officers can be a very surly lot.
A smile says the same thing in any language. Yes, we are all nice people but Malaysians do not have a monopoly on 'nice people'.
If Engstan hasn't been to Thailand, I would heartily recommend it. I find that many Thai people who cannot understand what on earth you're talking about, can often find the time to give you a smile.
You can leave a shop without buying anything after browsing extensively and still get a smile from the salesperson on your way out.
How often can you expect this to happen in Malaysia? Next!
