If I saw that there was a Walmart in town, I perked up. Consistent, low-priced and large number of grocery items. Likely better than an unknown, variable, often poorly stocked local grocery (or worse, groceries at a gas station/convenience store).
I also liked seeing the economic diversity of customers that I wouldn't see at home.
In larger cities, I'll choose other groceries if I can for better selection, if not better prices.
Of course, except for maybe Sprouts, all the places I shop emphasize ultra-processed corporte interests.
