I loved this sign, which I spotted at a medical centre in Dubai, because it seems to indicate that a semi-regular wallpapering of the bathroom has been going on, on a regular basis. It just indicates some serious frustration, you know? The illustration just adds punch. As does the pink fonts, varying in shade.
I was also tickled by the no-smoking sign, as the bathroom reeked of cigarettes.
The person who posted these signs must be very frustrated, indeed.
