A few weeks ago I was quietly sitting in the dilapidated waiting room at Leicester waiting for my train as comfortably the poorly designed metal benches allow, when, after multiple clear annoucements about a platform change a member of staff came rushing in and started interrogating each person individually about their travel plans, trying to ascertain whether we were there to catch the platform changed train; despite this being only a few minutes before the train arrived, well after the time that most people meaning to catch that train would have exited the waiting room.
Even worse, as I was listening to my headphones at the time, I expected that the staff member would simply pass me by, which he did not do; insisting that I remove my headphones to answer his queries! I was also sitting directly in front of the (tiny and poorly positioned) departure screen and, since I was listening to a fairly quiet audiobook or podcast, I had heard the annoucements clearly (although, granted, there is no way for him to have known this).
I get trying to make sure passengers get the information, but individually interrogating passengers in the waiting room including interrupting passengers who clearly aren't interested is surely going too far! Very weird indeed.
