Here at Knudsen, Inc. we never have a problem with refrigerator consolidation. Since our company's inception in 1981 we've had a valued employee who leads the charge to keep all leftovers in appropriate sized containers.
As soon as casserole portions can be downsized to smaller rubbermaid containers our CLO (Chief Leftover Officer) is on the job!
The benefits to an inhouse CLO are tremendous. We always have ample fridge space. We never have a problem with food getting old, since the CLO doesn't just reformat products into the right size tupperware, he'll toss outdated product as well.
Even on the road our CLO is on-the-job. As a houseguest he has been known to educate oblivious fridge owners on the merits of putting small things in small containers, etc. (think Grammy and her 9X13 casseroles with 1 serving left). It's a free service too, whether you want it or not!
Our CLO moonlights at 2 other freelance jobs, one paid position as the Founder of Partnership Capital Growth and also in a volunteer clergy position! His c0-workers and the church members are probably not aware of his special skill set!
We feel so lucky to have such a diligent CLO who is willing to work as needed but seems especially willing to take on the hard jobs (say right after a party and an abundance of food products need proper placement). No job is too big or too small for our conscientious CLO!
