When I was younger, sweets were offered everywhere in those red candy machines at the exits of supermarkets, in shopping areas and other public places. When I was behaving really well, I could sometimes convince my parents to give me a dime and buy candy or a little, worthless present that they also held.
Today with so many people addicted to sugar, I want to jump right in and establish a chain of walls with high quality sweets pretty much everywhere. I believe that for each fitness a country counts, a sweet tooth wall makes sense. Compare it with croquettes walls in the Netherlands. With some retro branding and the accompanying smell of sweets, this will prove a hit again.
