Not a rant at Southeastern per say

Not a rant at Southeastern per say, but still a rant about trains well train stations.
I catch my home train from Cannon Street as a lot of other sad commuters do we shuffle into the station just wanting to be out of London and back to our cosy happy existence somewhere else in the commuter belt.
Some of us cut it a bit fine to get the train due to having a job that means you get looked at funny if you leave at the correct pack up leg it time. (I am sure I am not the only one in this position, but I digress.)
You have 30 seconds to get through the station navigate the 2 open barriers out of 10 to get to your savour of a train home.
So in their infinite wisdom what do you think they do at Cannon Street.
At the top of the stairs right in front of the barriers they have mounted screens to tell you what platform to get.
Everyone who is not sure what platform to run to stands there looking up in the air as if the spaceship from V is hovering over London. Not something you want to navigate when you are in a hurry I can tell you.
Another sarcastic "well done" to the bright sparks who run the rail industry in this country.
Just makes you wonder what happened to common sense? anyone seen it laying around or found it stuck down the back of their sofa.
