Remember this idea? It was created by They for Coffee Connection (an old client of mine actually, we did Fax ideas which tells you how long ago that was). They used "WiFi headlines" to nudge people into getting another coffee, or maybe buy a tasty muffin - the customer would ask what the WiFi network was named and the barista could reply "BuyAnotherCoffeeAlready" and mean it. Very funny. So clever that They won Silver in the Epica awards 2008 with it.
