Double Pricing: Moral? No. Legal? You Bet!
One of the first things I learned when I was teaching was that many (if not most) Thais automatically think two things about every non-Asian foreigner: 1) We're rich, and 2) We're Christian. As my curious students pounded me with questions, I was always amused to see their confused looks when I told them the truth, shattering the preconceptions that they picked up from their parents, friends, or very, very silly Thai television shows. I proudly told them that I am closer to Buddhism than anything else and am most certainly very, very far away from being rich. However, the stereotype still persists, and is probably a large reason for the existence of double pricing in Thailand, a practice so outrageously illegal in North America that visitors are nearly always shocked/offended/angered/saddened to see it at nearly every tourist destination they visit.
