Never be rude & raise your voice by ASTRAMISH
We found that a lot of tourists from european countries ( not all & yes my parents are european/australian) tended to be very rude & treated the thais like slaves, when ordering food at eating places & whilst bartering. we found this extremely off putting & felt sorry for the Thais who had to put up with this unexcusable behavior.we went to the trouble of learning a little Thai & always respected that we were visiting another country. We didnt raise our voices or lose face as the thais say even if we were upset( like when we were bartering for a tuk tuk or shopping & we knew that they were trying to rip us off) we treated it all as fun & if u laugh & smile you will go a long way inj Thailand as opposed to being rude.I miss the beautiful warm hearted thais & their smile.
The only other country where i have felt welcome & at ease with the local people is Bali in Indonesia.
