In most American cities, going to the grocery store is kind of a pain. You have to drive somewhere, usually at least a mile or two. You have to find some place to park and walk across a huge parking lot. The store itself will be huge, if you're just getting three things you have to trek all the way across the store to retrieve them. And the lines at the checkout can be bad.

As I mentioned in another comment, I had the opportunity to live for a year in a very walkable neighborhood, with an excellent grocery store. It was convenient, it was small, the food was high quality, checkout was lightning fast. I found myself going there nearly every day and it was wonderful.

But once I needed to move back to a more car-centered city, the idea of doing this became once again unthinkable. Far too big of a chore to do daily.
