Nothing takes me back to my childhood like a Rice Krispies treat. I grew up helping my parents stock the aisles of their gas station and convenience store in the suburbs of Denver, where they sold everything from lottery tickets and cigarettes to hundreds of pantry items. While Mama and Papa retired in 2018 after operating the business for 35 years, I have vivid memories of the mini mart’s many shelves, one of which was neatly stocked with more than two dozen types of cereal.
