Why do SWR Staff Smoke in the Bike Rack area at Waterloo?

At Waterloo central exit where the bike racks are, the area is liberally plastered with no smoking signs. They are affixed to the walls and painted on the floor.

Not only do commuters and tourists ignore them, but your own staff join in with them.

What is the point of the signs? Surely company employees should be encouraging people to move off, and not to smoke in designated no smoking areas? It beggars belief that your own staff stand on the signs that they should be enforcing.

I don't particularly want to fight by way through smokers and inhale their smoke whilst I am trying to lock up my bike.
