With no entrance to the gents loo to be seen from this main approach, this set up could almost be mistaken for queues for relieving against the wall. In reality it's empty bike racks.
The gents sign correctly describes the building to which it is attached, so it's really just informational as opposed to directional. All it needs is an arrow to direct you to the right and the entrance is of course just around the corner.
There's also some subtle re-enforcing of the idea with the Shower sight right next to the down pipe and it's kink to the guttering.
