Usability in action. Not one but two extra signs have been required here to persuade the ladies that this really is the way in. What's gone wrong? At a guess, the height of the signs, the collision of too many signs (the baby, the shower... or is it a jellyfish), but perhaps the icons for men and women are just too similar. The two word sign 'Ladies toilet' forces the type to a smaller size, too.
Another thought - where do dads go to change their babies?
