How can you make such a statement without knowing my personal circumstances. Why do you draw the obvious false conclusion that I am a tourist?
I don't expect to get the same treatment as I Thai, I already said I expect to pay. But I do not expect to be deliberately discriminated against and deigned medication precisely because I am NOT a Thai.
Here is the dictionary definition of racism which I think you should read:-
rac•ism
1. a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usu. involving the idea that one's own race is superior.
2. a policy, system of government, etc., based on such a doctrine.
3. hatred or intolerance of another race or other races.
