A lot of these "tourists" should stay home. I like the fact that I can go int a BK or Starbucks every once in a while, but I do like the "adventure" of being in a different place. Thai people some of the friendliest people I have encountered while traveling in Thailand. BTW, fat old German tourists love to be in Thailand, behaving outrageously.
I feel that once should not be a an "Ugly anything". Unfortunately that label stuck to Americans.
