In my former bank call center, there was someone who used the men’s bathroom as a canvass for his “art”. The artist would go into a stall and redecorate it by drawing a large, crudely drawn smiley emoji in their own( I hope) poo.
This went on for weeks until the cleaning ladies refused to clean this up with the end result of the manager of the centre going in herself to clean it up.
Then it ceased and we were always left to wonder…
Will the phantom poo artist strike again?
