The lazy susan has been around for decades, if not centuries, as a component in dining tables. It is this rotating round thing at the center of dining tables, mostly in Chinese homes and restaurants. It makes dining easy and convenient because you won't have to reach for the food across the table. ~~
Having a lazy susan in the office is a clever and creative way of organizing your supplies in the office and even at home. Just spin it to get the supplies that you need.
