I googled it.
and was directed by my friend google to here.
which is why I am asking here.
to all those who have helped me today thank-you very much. I will sleep better tonight and will be off to Saigon soon.
To the Germans and lizards, you were half the reason I left the west to come to Thailand. You are just reinforcing to me I made the right decision. So thanks to you also.
And a tip. good manners go a long way in Thailand, being rude will get you nowhere.
