On our way home from a school excursion, we stopped at a roadside cafe to use the toilet and have a cup of tea.
Walking back to the bus, we passed a group of giggling girls, who called one of my friends over.
When my friend returned, she said that they had said, "can you please let your friend know she has toilet paper coming out of her pants."
OMTG I had walked through the whole restaurant with it there!
