Im a Bruneian who regularly visits Thailand (monthly). I;ve not seen any differences between Thai practices and what is done in Brunei in terms of 'table manners'. As the Thais, we do share our food by offering what we've ordered and may choose to accept/ refuse food offered to me. Same thing happens when Im with Thai or indeed, Malaysian, Indonesian, Vietnamese, Cambodian, Laotian, or Filipino friends. No one takes offence at all, in fact it's 'expected'. I sometimes do put some of my food on friend's plates (usually when eating out and ordering different dishes each, not when we all take from the same buffet). The reason we do it is that we often think people would like some but are too polite to ask (it's not Asian to ask). I suppose it is a South-East Asian thing. But my Korean and Japanese friends do the same too. I guess, to be safe, always ask/ offer first.
