A walkable city means groceries stores at a walkable distance, which means while walking home from wherever you were, you just buy a couple of things missing for tonight's diner. You're at home, no more sugar for a cake? just a 5 min round trip.

Ironically even in my suburb we have 3 grocery stores about a mile away each. But I only like going to the store once a week. Daily would be a waste of time.

At those distances I would never go buy groceries by foot either.
