I got a membership card at a car wash.

Because the little girl washing the car would use her thumb to turn a couple of extra times at the spot where I held the steering wheel.
I said, "Your technique is pretty professional."
She said, "Bro, your palms sweat easily, and this area can't be cleaned thoroughly. If you hold it, it will slip."
Later, I went to wash my car twice a week.
My friend asked me, "Is your car that dirty?"
I said, "It doesn't matter if it's dirty or not; what's important is that there’s still someone in this world who remembers that my palms sweat easily."
