On the Japanese practice of "machizemi" where shop keepers hold learning seminars on things related to their business specialty resulting in increased sales and visitors, revitalization of shopping districts etc. An effective way of competing with malls. A knife shop teaches customers how to sharpen their knives, a restaurant teaches visitors how to cook their speciality, a tea store teaches people who to properly brew tea, etc. So many great stories and ideas here. Should be applicable anywhere in the world.
