Haven't been to Kroger, or as we used to say, Krogers, for quite a while, but I assume what this means is that much of their floor space is taken up by low-quality prepared food and over-the-counter medicines. But that's true of every large grocery in the US.
Meat counter, extensive selection of frozen food. Good amount of space for non-food items, like over the counter medicine, schools supplies, cleaning supplies, personal care items.
Maybe a pharmacy, maybe not, depending on the store.
In Northern California, it seems Safeway and Lucky are the top ones, and of course Costco. Also 99 Ranch, often called Ranch 99, which is aimed at Asian food customers. There are other smaller chains and individual stores.
Whole Foods, or TJ's. Can I buy a mop, a bottle of Tylenol, and two quarts of motor oil? Not a chance.
I would say Kroger isn't a real supermarket, it's a junk food market and pharmacopia.
