Why do you suppose that foods contain potatoes are not found together in a grocery store?

Foods that contain potatoes are often found together in a grocery store. For example, in the frozen food section, you will find tater tots, french fries, and hash browns all in the same area. In the canned goods section, you will find canned potatoes, potato soup, and potato salad all together. In the produce section, you will find fresh potatoes, as well as other vegetables that are commonly used in potato dishes, such as onions, carrots, and celery.
