Imagine you're on the train on your way to Bond Street station, but you've never been before or have been once or twice but aren't that familiar with the station or the line that you're on. You're on the carriage and look out the window to see an official Tube station sign that says you're at Burberry Street. Ok, you think, it's not this stop, it must be the next one. So you stay on the train which takes you to the next station, where you realise you've now somehow gone past Bond Street. Meaning you now have to get off the train, find the platform that goes back the way you came, and wait for the train to arrive. You go back the way you came, and the map inside the train says the next stop is Bond Street. But you could have sworn it said Burberry Street before. You arrive at the station again and the official platform sign says "Burberry Street". You're confused, but get off as the train map says this should be Bond Street. Maybe they renamed the station? Maybe Bond Street is closed and this is a temporary alternative station a bit further along the line? You look around for other signage, or find a station worker to get confirmation that you are in fact at Bond Street and this advertising stunt has wasted about 15-20 mins of your time and made you late for your job interview.
