Thermal lunch boxes

I pulled open the door on the refrigerator at the office to put my tupperware full of rice and broccoli on the shelf, and was struck with amusement by what I found. The fridge had several insulated lunch boxes taking up shelf space. Now you tell me: if you have a container designed to keep the inside air in and the outside air out, and the inside temperature consistent in spite of the temperature of the outside air, why put a closed, thermal lunch box in the refrigerator???

There must be a ton of metaphor opportunities here. Not trusting the container to do its job. Not paying attention to how the container's being used. Unnecessarily taking up shelf space. Overcompensating for what might possibly be a small loss of some essential quality (cooling). Under-utilizing the equipment/tools/gifts that we have (using the lunch box simply as a lunch box without the cooling function).

With regard and apologies to my colleagues, it's a thermal lunchbox! What thermal lunchboxes do you have in your fridge??
