Have you ever come home from a night of drinking, only to find the refrigerator bare other than a few jars of horrid nasty Asian pickles?
Growing up, my mom was like that. She still is. Dad had to hide cans of sardines in the garage and chocolate bars in his glove box. He finally completely took over the grocery shopping and most of the cooking in their 15th year of marriage, poor guy. To this day, just in case, I try to keep a locking cosmetic case stocked with tasty, non-perishable things like Vienna sausages, a hermetic Dinty Moore with beef, carrots and potatoes, latte in a jar, pepperoni, antipasto in a jar, a chocolate bar, dried fruit like dates/figs, nut mix, wasabi peas, and waxed cheese.
