I would think most Americans couldn’t respond accurately. If you do your weekly shopping at Waldbaum’s, Publix, etc you’re also buying toothpaste, toilet paper,soap,garbage bags , foil etc. I don’t sit down and separate what food I bought from what dry goods etc I bought.Unless a family does all their food shopping in one place and the rest in another, say Costco or a $.99 Store, this survey is pretty much worthless.IMO
You are so right. When I was taken shopping by my grandmother in the 50s, grocery stores had grocery products, meat, produce, cleaning liquids/powders and laundry products. Today, "grocery" stores such as Giant, Food Lion or Safeway have pharmacies, over-the-counter drugstore items, clothing, toys, floral arrangements, books and newstand items, cooked foods, lottery tickets, stamps, lawn care items, hardware, auto care items, dorm furniture, gifts, candy, pet supplies, office supplies, a fish market and enough to furnish a 1950s ice cream parlor and soda shop.
