I’ve heard that too. However, they can put the foods any place they want. It’s their store! It’s up to the individual to choose what they want to buy then go home and cook or bake it.
That was understood without saying.
Produce, meat. dairy is usually along the walls in most stores...junk foods on the shelves.
Have you checked out cereals lately? Most of them are sugar-coated ---literally.
Breads are my downfall. I loooove hot rolls especially...and they call for butter!
