I have never heard of any other country where tourists get their heads stomped in by 9-10 locals. This is purely a Thai thing. Never happens in Cambodia, Vietnam, Laos, Malaysia, Indonesia, Singapore, Japan, Korea, Philippines...not even in China, where they openly hate foreigners...why is that? This is something special to Thailand, and it's a damn good indication that just barely under the surface, Thais utterly hate farangs.
