In the US bread comes pre-sliced in a plastic bag. You can pick up this kind of bread nearly anywhere, from a convenience store to a fill-up station or a pharmacy. Bakeries which put out product that Europeans would consider bread are almost exclusively found inside grocery stores. This bread is slightly more expensive per weight. Grocery stores, like most commercial establishments in the US, can be hard to get to without a car, and public transport, if exists outside the few major cities, typically has low frequency and poor coverage of residential areas. UHT milk does exist, but most people don't know about it, and it's expensive. Most milk sold isn't shelf-stable and needs to be refrigerated the entire time. You make a good case with the salad, though.
