Looks like they have rotated the staff - certainly looks like some of the old faces have now gone.
I remember a number of occasions which drove me crazy. This one in particular was on a day there were virtually no overground trains running, not that the boards showed this. Having let two London Bridge trains, I went to ask the guy on the platform with the loudspeaker (I think he was moved to Forest Hill after a while) who said of yes, there has only been one Overground Train since 6am. It was around 7.30am now. So the passengers had to update each other, as he just shrugged his shoulders whilst getting an earful form someone else. Next train was rammed and no-one could get on, train that had passed before had a decent amount of space. Proactive he was not.
