Very sensible post. I have not raised my voice to any Thai's, not even my wife, but she is very highly educated and clever, except for an immigration officer, and that was only in retaliation to his attitude to me. He's not going to give me a thumping. I have stopped lot's of them both men and women from jumping in front of me in a queue without shouting, I just put my arm in front of them, as experience has taught me to always watch for them. I know I said I would shout back at them, but I have changed my mind on that.
