Underwater view of a coalhole

Recently, our family had a very passable Thai lunch in Krua Anne cafe in the bijou Kensington Gardens in Brighton's North Laine. After the meal, I needed to use the 'facilities' and was directed to the basement where I found an amazing mural covering the walls and ceiling, depicting a tropical underwater paradise of colourful fish, vibrant coral and wibbly seaweed.

I noticed a circular indentation in the ceiling and a thrill shuddered through me as I realised that I was urinating in an old coal cellar underneath the pavement and the inundation was the hole left after the cover had been removed.
