Who stole Sunday?

My plan for the day, was to go walking in the sun with my lovely wife however......
Following a phone call last night, I spent the day chasing a leak! It turned out to be a 5p seal, in the most inaccessible place. This was my only view, thank goodness for cameras on phones, to give me a view of the unseen.
Whoever thought back to the wall toilets a good idea, never installed or serviced them
