How would you handle demolishing the wrong building?

It's Friday afternoon, and time for a bit of humour. Although, for the person trying to use his bathroom in the video below, I don't think there was a funny side.

A demolition carried out in 2008 was clearly not planned properly and a section of building demolished that shouldn't have been. The first the demolition crew knew about it was after tearing down the outside wall of a building revealing a bathroom. Shortly afterwards a surprised head pops round the door wondering what all the noise is about.

After a short conversation things get even more bizarre. One of the crew decide to start cleaning away the rubble, and then gets some boards to replace the wall.
