Can supermarket models be split into 2 main categories?

Supermarkets are usually laid out for a couple of sets of shoppers: The Produce and raw meat sections, for people that Actually cook, the frozen food and the canned stuff for the lazy ones, and the cereal isle for those that have kids. 

The rest of it, like cleaning supplies, pots and pans are just there because, well they Have to put it there. 

I don't find that to be true of most run-of-the-mill grocery stores.  Most have a combo IMO.

I'll admit I avoid Trader Joe's as it is mostly ready meals, boxed, packaged, snacks, junk.    You can go in there, spend $75, come home and still have trouble making an actual meal for dinner.
