A new barber shop opened downstairs in the neighborhood, offering a special opening price of 38 yuan for a haircut.

I went in.
The girl washing hair said, "Your scalp is a bit sensitive, I suggest doing a check, it's free today."
I said no need.
She didn't stop: "It's really free, you don't have to do it, just take a look."
I ignored her.
After washing, I sat down, and the barber came over, looked at my hair for three seconds first.
