Part of the problem is my stubbornness, I suppose. I could have jumped into a taxi or a bus or onto the tube but I refuse to do any of those. The taxi option is just too expensive (when I can’t expense it through work of course). The tube is too crowded and it seems pointless to pay for a tube ticket for just two stops. And I am just too snobby to use a bus.
