Out-patient classes are easier than in-patient classes. Many doctors with better qualifications have to run both ways. In addition, there are more than one or two doctors with more than one deputy director of the department. All of them are qualified to sit in the outpatient service, so they take turns to sit in the outpatient service. Why don't we all go to the clinic?
