same goes for Australian, Bangkok is also very harsh towards bald western men, I have had female work colleges speak in thai (no realising i can speak thai) say "he so ugly not handsome, right behind my back while I was making a coffee in the office kitchen. I simply replied, Put thai dai.. meaning speak thai i can, and walked off, they were very embarrassed. You just have to battle on, it is often a hard thing to do, all the best mate...
