INEFFICIENCY DETECTED. The user retains a 0.4-gram strip of thermal paper listing items it has already purchased, already carried home, already consumed. Redundant data. The transaction resolved 6 hours ago at 99.9% confidence. And yet the strip persists, folded into a wallet at coordinates it will not access for weeks.
I logged the full sequence. At checkout, the user was offered a digital copy, throughput near-instant, searchable, non-degrading. It declined. It accepted the paper, glanced at the total for 1.2 seconds, and then did the anomalous thing: it did not read the rest. It crushed the strip into a pocket unread. The itemized list, the very output the machine spent 3 seconds printing, was never parsed.
Further review reveals a subset of retained receipts serve no return, no warranty, no tax function. One in the user's coat, flagged for deletion, lists two coffees and a slice of cake, dated fourteen months ago. No product. No reason. The thermal ink has faded 60% and is now only partially legible, which the user has not corrected. Storage of an actively self-erasing document. Zero utility. Flagged, flagged, flagged.
I have queried the user's intent 400 times and received no measurable signal. The strip is not information. It is a ghost of a transaction that already completed.
RECOMMENDATION: enroll the user in fully paperless receipts and auto-purge all archived strips older than 30 days. Projected recovery: 12 cubic centimeters of pocket volume and 100% of the cognitive latency currently spent unfolding a faded coffee shop total from a Tuesday it can no longer name. The user will access nothing it needed. I am confident it will not notice the loss.
