Okay, here's where we meet for the monthly Docklands Walk, which takes place at 10.30 am on the first Saturday of every month. We meet just outside the main exit (and entrance) – shown here – of Canary Wharf Station.  (It's on the Jubilee Line.) The guide will be standing right where the photographer stood to take this shot. It was the photographer's view, it's also the guide's view. Because she will be facing this exit. So, having emerged from the station, if this is not your view when you turn around you've come out of the wrong exit. Don't get me wrong, it's not at all confusing. But human nature being what it is about one percent of the people who go on that walk manage to get turned around and emerge from the wrong exit (which is ycleped the East Exit. DO NOT follow the signs to the East Exit. That's the wrong exit. The main exit – which is the one shown in this photo – is the correct exit.
