When I was a kid, tagging along with my Dad on the weekends as he ran his errands, it seemed he could never help himself to keep from merchandising. We would stop at every grocery store that was even remotely on the way for the current errand. We'd get out, walk the store (at least the Kleenex section because at the time he sold Kleenex products wholesale), and merchandise the section.
I like to tell people I threw my first case at 4 years old, and it's one of my first, and most cherished memories. Shoulder to knee. (My shoulder, his knee) with my Dad, slinging Kleenex and "tryina' make a dollar," as he used to say.
