Thinking back to when I worked away from the house, I think that the one thing that I would have appreciated was the dietary freedom.
I don't mean that in terms of grabbing a snack whenever I want a snack, I mean being able to eat whatever lunch I want without struggling to find something that was half way edible and that tickled my taste buds. Living and working in a small town without transport of my own left my lunch choices severely lacking and workplace politics made me reluctant to take food in to put in the shared fridge.
