The shop I used to work at had a Seven-Eleven next door (in the same building),

and there was a staff member who was always buying self-service drip coffee from there.
I had been wondering,
"Why does this person always have those curly hairs floating in their coffee?"
but it turns out
it was just the seam of the paper cup.
