The rest is to prescribe medicine, which is expensive, and everything is on the cost of medicine.
It is so expensive to buy medicine. If you don't buy it, people may not give you a good look. It's all a course of medication, and you can continue to consult after using it.
Hospitals have this logic.
Doctors in the hospital open dozens of dollars and sell hundreds of dollars, all of which have commissions! So it is difficult to see a doctor.
