I walked passed a shop recently that prominently displayed such a sign on the front door (no, they were not selling air conditioners - which would have made the sign slightly cute).

In the context of Sydney, how can this "feature" possibly help this shop stand out and attract customers? Is this not feature-advantage-comparison gone mad?

What can we expect next as compelling reasons to go into a shop? "Fully Carpeted", or "Breathable Air Inside", or "Flushing Toilet"?!!!
