I used to drink on a narrowboat called the Tollesbury Barge in the Millwall Inner Dock. They did a mean egg, chips, sausage and beans too.
They had a board proclaiming how the boat had survived the Blitz, Dunkirk and a number of other adversities. It didn't survive the local redevelopment, though.
Shortly after a developer of some luxury flats tried to get the boat moved, unsuccessfully, as he thought it was an eyesore (visible as it was from his floating showroom), the boat suddenly found itself listing heavily to one side. And that was the end of that.
Obviously the two events were unrelated, and I am more than happy to accept that this was the case.
