Our coworking kitchen has been a messy place. Dishes standing everywhere but in the dishwasher, the dishwasher itself being only half emptied, used coffee mugs all over the place. One day one of our coworkers, [Jan](http://twitter.com/janl), had enough, and he changed it all with a single piece of paper:  Since then our kitchen has magically become much cleaner. People empty the dish washer and everything. Inspired by the success, yesterday I tackled the next problem: food becoming alive again and walking around in the fridge.  We'll see how that goes.
