A small fraction of Americans shop daily for food. For the majority, it's a weekly (or even less frequent) occurrence.

And no, fresh bread is not really a thing, outside of a few urbanish settings. A healthy proportion of bakeries don't even sell bread - only pastries, cakes, etc.

Americans almost never buy fresh bread. We buy packaged bread with preservatives that lasts about a week (much longer if frozen or refrigerated).

Most of us don't go to the grocery store more than once or twice a week. When we do, it's often a big purchase that you can't carry back in your hands or on a small bike. You'd need something with more cargo space.
