If you log into a loyalty account for a Kroger store (QFC, Fred Meyer, others)... you see similar transaction lists. This is extremely normal for retailers.<p>Also, machine learning can create shadow profiles for people, even those who don't have a loyalty account. (E.g., a purchase occurs every Friday around 5:30 and buys a specific beer and specific brats...).<p>This is all <i>obvious</i> stuff to me, but, also, people might not be aware that every interaction - touchpoint - on a big enterprise is recorded.
