Experience of a scary doctor and long waiting time at Yeollin St. Mary's ENT Clinic

I visited Yeollin St. Mary's ENT Clinic, located near Guro-gu Office, specifically between Guro Station and Daerim Station.
There really aren't any ENT clinics nearby.
It is true that there are many people with disabilities, as there are not many internal medicine clinics and no ENT clinics.
The wait is no joke. I recommend allowing at least two hours for your visit.
Clinic hours are considered night clinics starting from 5 o'clock.
The nurse was just okay, but the doctor was really scary. I don't know what to say. It is really inconvenient that there are no ENT clinics in this Guro-dong area. There has never been a time when I saw improvement immediately after a consultation. They tell me to take it for two days and come back, saying they will change the medication, but the second dose is not much different, so I don't understand why I have to come back. Patients are busy too, but the doctor seems to think only they are busy.
