The emergency room at Ewha Womans University Seoul Hospital is the worst

My baby caught the flu, and the fever spiked to 39.5°C in the early morning. Even after taking antipyretics, the fever wouldn't go down, so I rushed to the emergency room in a panic, but they actually got angry at me.
All they said was that there isn't much they can do for a baby with a fever. They told me that even if the baby has a febrile seizure or if the fever doesn't drop, there's nothing they can do, so they'd just give me Tylenol and told me to go home? I can't believe they said this.
Shouldn't they at least use a stethoscope once? They actually lost their temper, and I was so dumbfounded that I was speechless.
The emergency room wasn't even crowded with urgent patients, and I wasn't even the one being angry... I went to the ER with a baby burning up with fever, only to end up getting scolded by a professor.
In the end, I went to the ER at this hour just to have the temperature checked twice and left. I told them I already had Tylenol and walked out. I feel truly terrible.
Please do not go to the Ewha Womans University Seoul Hospital emergency room. And please be careful with the flu.
