These 24-hour professional toilet unclogging companies lately...

It seems like anyone and everyone calls themselves an expert..
I moved into a new house with two bathrooms, and one of the toilets was completely clogged.
I tried everything from plungers to shampoo, but nothing worked,
so I called a professional service company.
They advertised "zero call-out fees," showed up in professional-looking clothes
with professional-looking equipment, and started tinkering around with it,
only for the water in the toilet to turn pitch black.
Then they told me the main pipe was clogged and that they had to remove the toilet to fix it.
The price they quoted was 500,000 KRW...
Sigh.. since I have two bathrooms, it wasn't an emergency,
so I took their business card and told them I'd try a bit more myself and call them back.
After they left, I looked up a "toilet auger" online, bought one, and tried it. Within 30 seconds, the stuck toothbrush and clumps of toilet paper came out, and it was cleared..
This is the perfect job for scamming elderly people or women living alone.. Everyone's an expert these days.
