How long have you been in Thailand, and Thai culture? Making a scene DOES NOT work in Thailand, and Thai culture. What you need to do is to smile, laugh, and make a joke about it.
I got into a traffic accident with a guy (his fault), we got out, exchanged information, smile, and laugh about it. Then we went to the police station a few days later with the insurance people, smiled and laugh about it too, and I got my back light replaced. I know darn well if I got angry nothing good would happen. Nothing.
