I am a westerner and I was very surprised last week while at the local hospital to see how we are all treated in comparison to the natives. Although I am sure I fared better than other expats it was still crap service and they are only interested in the money. When I asked the receptionist to log my appointment onto their web site she told me they don't bother because the people that come there are a "different" class of people and it doesn't do any good to use the available services. Although I had an appointment I waited 3.5 hrs for my turn and then they asked me why I was there. The were numerous natives called in first to the doctor's office although I was the 5th person in line at the cashiers and they could not possibly have got there first. And it was wonderful to see all the natives stop at the doors and hold private consultations with the doctors although they had no number.
Good luck in your pursuit to good treatment.
