Well, as you walk between the HEX ticket office and the Delice de France/Upper Crust towards platforms for the HEX, there is something beong done there, with hoarding and boarding up. Maybe that is something to do with it. Although I certainly think that it could be probably the worst place to put anything like that... the space is narrow and can get congested with people going to and from the HEX and also people following the pink line on the floor to the H+C line...
Will have a scooby in the morning and see if I can see anything...
On a similar point, that I have seen when looking at the website... I did not realize that the WiFi is now free!
