Hotel toilet paper folding
Hotel toilet paper folding is a common practice performed by hotels worldwide as a way of assuring guests that the bathroom has been cleaned. The common fold normally involves creating a triangle or "V" shape out of the first available sheet or square on a toilet paper roll. Commonly, the two corners of that sheet are tucked behind the paper symmetrically, forming a point at the end of the roll. More elaborate folding results in shapes like fans, sailboats, and even flowers. Toilet paper folding is also known as "toilet paper origami" or "toilegami". The practice has been considered an emblematic example of a meme copied across the world from a hotel to another, until it became common. (Wikipedia).
