It doesn't seem to require any great wisdom to have a bright and clean store with fast-food service, but when you link this simple product together with a trademark, powerful name recognition, and high quality control, the result has swept the globe.

永保明亮歡樂的店面設計和促銷手法也未必有多大學問，然而當這麼簡單的商品融合了專利註冊、品牌實力，以及嚴格的管理品質後，竟可以吃遍全世界，讓全球二萬多家加盟店替它壯大事業版圖，還無條件地永遠奉上百分之五營業額做為服務費！
