Do you stand on the right on the escalator in John Lewis or your local shopping mall?

Did “Please stand on the right” originate on the London Underground? Like Pavlov’s dog, we’ve been gradually conditioned to do this. And why is it the opposite to our roads in the UK, where we drive on the left?

One thing’s for sure wherever you are. If you’re not standing on the right there will always be someone in a rush trying to get by.
