STAND RIGHT, WALK LEFT. Perhaps it's reversed in the Tube. No matter the location, however, there will be clueless newbies impeding the flow of commuters out of the station. That's a regular gripe in the letters to the Chicago commuter newsletter (a waste of effort, in my view, as it is the occasional riders who haven't figured out that the regular riders take the last possible train, and those occasional riders probably don't read the newsletter, which is out of stock shortly after publication). I wonder, though, is the phenomenon more common at tourist destinations. In Washington, DC, disembarking passengers at L'Enfant Plaza or Pentagon have the drill down, but at Archives or Union Station, the rogue escalator user is common, and probably a visitor.
