Waiting until the last possible minute, they experience that sudden wake-up call from the stomach, only to find that their modest kitchens are totally unprepared to answer that call. Then there's the issue of condiments. Very old condiments inhabit bachelor fridges, like artifacts in a paleontologist's lab. All in brands that mom used to buy. It's very comforting to bachelors to have recognizable shapes, sizes and brands in their refrigerators.
Condiments appear to occupy mythic status.
Like the Roman gods of the hearth, their function appears to be purely ceremonial. They are not actually consumed except in emergencies. In fact the entire category of pickled foods is archetypal. The quick fix that substitutes for laborious, complex preparation beyond the bachelor bandwidth. Grilled cheese sandwiches and omelets are the designer foods of bachelor existence.
