The interactions with not only the Dr's but the staff is far more respectful, caring and relaxed. The behaviour in the waiting rooms of the patients is far more civilised, there is no anger/aggression towards staff or sign of one persons issue being above that of another (its happened where a parent has had a sick child and the receptionist has asked several people if they mind being pushed back in the queue, no problems). If a persons phone rings they more often than not, switch it off or walk outside to answer.
Maybe it's as much a cultural thing as a socio economic thing but I also have frequented many middle eastern eateries where the opposite of the above is true.
