A tripod in the foot tunnel! Not the most considerate thing ever considering the lack of space. Everybody is in a hurry because it feels like a bazillion litres of River Thames is about to breach the walls and you really want to exit asap. Not to mention the really angry jobsworth guy operating the lift at the time.

Low shutter speed to catch the movement. I kept meaning to go back but it was shut for ages. It may have been renovated by now. In 2008 it felt like a Victorian throwback.
