95% of people favour the broom as a technology in Tidytown. 5% have bought into leaf-blowers (but no-one bought the exact same model, or has the exact same yard). In fact, as long as anyone can remember, the council have issued brooms to everyone, but only ever experimented with noisy leaf blowers. Imagine how hard it would is to be a leaf blower salesman in Tidytown. Everyday its your job to get Broom owners to change their mind and buy the model you sell (and you only sell one kind), while at the same time, the council still hand out brooms freely and frequently to everyone. Even worse, they have something wield at you as you knock on the door. This is why in Tidytown – Leaf blower salesmen carry a katana.
