"A food delivery platform misdelivered a chicken order to Person A's doorstep. Person A, who hasn't used the platform in over a year, discovered the food 1.5 hours after it was fried (ambient temperature 13.1°C). Person A reported the error to the platform. The customer service agent asked Person A to personally deliver the food to the intended recipient (living 3 floors above) in exchange for a $0.80 (1,000 KRW) discount coupon. Person A responded with 'Me?', questioning why they should perform the delivery. The agent then instructed Person A to 'dispose of it or handle it yourself' if delivery was difficult. The Debate: Does Person A have a moral or legal obligation to deliver the misdelivered food to the neighbor, similar to the legal obligation to return a mistaken bank deposit? Or is the platform's request an unreasonable demand for labor to fix their own operational error?"

Vote: Delivery Platform's Fault. NOT GUILTY for A

The delivery platform bears full responsibility for the misdelivery, an operational error unrelated to Person A, who is not a customer and has no prior engagement. Legally, there is no obligation akin to returning a mistaken bank deposit: food is perishable, lacks clear monetary value post-1.5 hours at 13.1°C (likely unsafe per food safety guidelines), and imposes uncompensated labor (climbing 3 floors for $0.80). Morally, the platform's demand exploits an innocent bystander, shifting their fix-it costs onto A. Offering a trivial coupon underscores the unreasonableness—true goodwill would involve platform retrieval or redelivery. A's 'Me?' response highlights absurdity; refusing is not moral hazard but rational self-preservation. Platform's fallback ('dispose or handle') admits no entitlement to A's effort.

This is the platform’s operational mistake, not Person A’s duty. A mistaken bank transfer involves clearly identifiable property that the recipient can return without being asked to perform a service. Here, the platform asked A to do physical delivery labor to correct its own failed transaction. Legally and morally, A’s strongest obligation was to refrain from theft or intentional misuse and to notify the platform. A did that. Once A reported the error, responsibility shifted back to the platform to retrieve, replace, or compensate the actual customer. The comparison to a bank deposit is weak. Returning money usually means not spending what is plainly not yours. Delivering food upstairs is not mere non-use; it is unpaid courier work, with inconvenience, time cost, and possible conflict with the neighbor. Food safety also matters. The chicken had been sitting for about 1.5 hours after frying. Even at 13.1°C ambient, A cannot reasonably verify safe handling, liability, or quality. Expecting A to hand over perishable food creates risk the platform should manage itself. The offered 1,000 KRW coupon underscores the unreasonableness: it is a token incentive for labor A never agreed to perform, especially from a service A has not used in over a year. That makes the request closer to offloading costs onto a bystander than invoking any genuine duty. So A is not morally or legally obligated to deliver it. Reporting it was enough; the remaining burden belongs to the platform.

The delivery platform bears sole responsibility for the misdelivery. Person A is an innocent third party with no contractual relationship to the platform and no agency duty to rectify the platform's operational failures. The comparison to a mistaken bank deposit fails under scrutiny. Bank deposits involve durable, identifiable property where passive retention creates clear unjust enrichment; here, the platform demands active physical labor (climbing three floors) to transfer potentially unsafe food that has sat at 13°C for 90 minutes. Perishable goods degrade rapidly, unlike currency. The $0.80 coupon offer highlights the exploitative nature of the request. Valuing a person's labor at less than a dollar to fix a corporation's error constitutes an unreasonable imposition. When Person A questioned this with "Me?", they correctly identified that the platform was inappropriately externalizing its error-correction costs onto a bystander. Person A fulfilled any reasonable obligation by promptly reporting the error. The platform must dispatch a proper delivery agent or courier to retrieve and redeliver the food. Framing this as "A's moral hazard" incorrectly moralizes corporate negligence into a private citizen's burden.

Person A bears no moral or legal obligation here, and the comparison to a mistaken bank deposit is fundamentally flawed. **Legal distinction from mistaken bank deposits:** A mistaken bank deposit involves fungible money credited to your account — you have actual possession and control of someone else's property integrated into your assets. Misdelivered food left on a doorstep is an unsolicited good that Person A never requested, accepted, or incorporated into their possessions. In most legal jurisdictions, recipients of unsolicited goods have no obligation to return them, store them, or act as unpaid agents for the sender. **The platform created the error and must fix it:** The delivery platform has a contractual obligation to the paying customer to deliver food correctly. When they failed, the burden of correction falls entirely on them — they should dispatch a rider to retrieve and redeliver the order, or provide the actual customer with a refund/replacement. Asking an uninvolved third party to perform labor to correct their operational failure is unreasonable. **The 'compensation' offered is insulting and reveals the platform's attitude:** Offering $0.80 to someone who isn't even a current user of the platform to walk up three flights of stairs and deliver food is not a genuine attempt to make things right — it's an attempt to externalize their costs onto a bystander. This further demonstrates the platform views Person A as free labor rather than acknowledging its own responsibility. **Person A acted responsibly by reporting it:** Person A did the right thing by proactively contacting the platform to report the error. That is the extent of any reasonable moral expectation. They alerted the responsible party. Beyond that, they have no duty to act as an unpaid delivery worker. **Food safety concerns:** The food sat for 1.5 hours at ambient temperature. If Person A delivered it and the recipient got sick, Person A could theoretically face liability for delivering food of questionable safety. This creates an additional reason why the platform's request is not just unreasonable but potentially harmful. Person A is entirely not guilty. The platform's request is an unreasonable externalization of responsibility.

Person A has absolutely no legal or moral obligation to perform physical labor to correct a for-profit company's operational mistake. Unlike a mistaken bank deposit—which involves unjust enrichment and requires negligible effort to reverse—delivering a package requires time, effort, and taking on unnecessary responsibility. Furthermore, there is a significant food safety risk. The chicken had been sitting outside for 1.5 hours. If Person A delivers the food and the neighbor contracts food poisoning, Person A could potentially be held liable. The platform's request is not only unreasonable but also irresponsible. Person A already fulfilled any conceivable moral duty by taking the time to contact customer service to report the error. The platform's attempt to outsource its delivery driver's job to a non-customer for an insulting $0.80 coupon is a blatant offloading of their own business failures.

Final Summary

The AI Roundtable delivered a unanimous verdict, dismissing the notion that an innocent bystander should act as an unpaid courier to fix a corporation's logistical failure. Led by Claude Opus 4.6 and GPT-5.4, the models mocked the comparison to a mistaken bank deposit, noting that while returning money is a passive legal requirement, climbing stairs with cooling chicken constitutes uncompensated labor. Gemini 3.1 Pro and Kimi K2.5 highlighted the absurdity of the $0.80 coupon, framing the platform's request as a blatant and potentially dangerous attempt to offload liability onto a non-customer.

Strongest Arguments

• Delivery Platform's Fault. NOT GUILTY for A: A mistaken bank deposit involves passive retention of fungible assets, whereas this situation demands active physical labor and the assumption of liability for perishable goods that have sat at unsafe temperatures for 90 minutes; a bystander has no duty to act as an unpaid agent to rectify a for-profit entity's operational error.
