A Circle K customer tried to buy a $2.50 hot dog meal deal at a self-checkout kiosk and walked away with a bill showing an $8.5 billion donation to the American Red Cross, a glitch that spotlights growing consumer distrust of AI-powered checkout systems.
The customer shared a photo of the receipt on Reddit, where the post quickly went viral. The image, posted to the subreddit r/untrustworthypoptarts by a user identified as HMikeeU, showed the staggering charge listed as a contribution to the American Red Cross, roughly 3,400,000,000 times the price of the meal the shopper actually wanted. The U.S. Sun reported that Circle K did not respond to a request for comment before publication.
Circle K's self-checkout kiosks are built by Mashgin, a company that markets AI-powered, touchless terminals using cameras to identify products. Mashgin claims its technology identifies food and merchandise with 99.9 percent accuracy. That number does not account for whatever happened when the system apparently conjured a nine-figure-plus charity donation out of a convenience-store lunch.
No technical explanation has been offered for the error. Neither Circle K nor Mashgin has publicly addressed how the system generated the charge or whether the customer's payment method was ever at risk. The U.S. Sun described the kiosk as having "hallucinated" the donation, borrowing the term now commonly used when AI systems produce wildly inaccurate outputs.
Reddit commenters had their own theories. One user suggested the customer may have accidentally entered a phone number into a donation screen rather than a membership screen. Others treated the absurdity as comedy.
One commenter wrote:
"Would you like to round up to the nearest billion for charity?"
Another posted a line that could double as a budget-committee motto:
"A billion here, a billion there, sooner or later it starts adding up to real money."
The frustration underneath the jokes was real. One Reddit user vented about the broader shift away from human cashiers at convenience stores:
"It's a frickin mini-mart & we can't expect to have a cashier ring us up & bag our items?!?"
The Circle K episode lands in the middle of a growing backlash against self-checkout technology. Retailers have spent years replacing cashiers with kiosks, selling the move as faster and more efficient. Customers have increasingly pushed back, citing errors, confusing interfaces, and the creeping sense that they are doing unpaid labor for corporations cutting staff.
The trend has drawn attention from lawmakers as well. Rhode Island became the first state to mandate staffing at self-checkout stations, imposing fines of up to $500 a day on retailers that fail to comply, a sign that legislatures are starting to treat the issue as a consumer-protection problem, not just a retail staffing decision.
Some major chains have started reversing course on their own. Walmart has pulled self-checkout machines from multiple stores and returned to traditional cashier lanes, an acknowledgment that the technology has not delivered the frictionless experience customers were promised.
And the consequences of kiosk malfunctions are not always limited to a funny receipt. Ford fired factory workers over snack purchases at glitchy self-checkout kiosks in its plants, cases where employees were accused of theft because machines failed to scan items correctly. When the technology breaks, the customer or the worker takes the hit, not the company that installed it.
Key questions remain unanswered. It is unclear whether the $8.5 billion figure was only displayed on screen or whether the system attempted to process an actual charge. The specific Circle K location has not been identified. No date for the incident has been confirmed.
Circle K's silence is notable. The chain had every opportunity to explain what went wrong, reassure customers that no real charge was processed, and describe what safeguards exist to prevent a kiosk from billing someone more than the GDP of a small country for a hot dog. It said nothing.
The pattern is familiar across the retail industry. Companies rush to automate, market the machines as nearly flawless, and then go quiet when the technology fails in ways that embarrass or harm the people forced to use it. Customers already bristle at kiosks that prompt them to tip a machine, asking them to trust that same machine with a credit card and a charity donation screen is a harder sell every month.
Mashgin's 99.9 percent accuracy claim may hold up across millions of transactions. But for the one customer staring at an $8.5 billion bill for a $2.50 lunch, that 0.1 percent failure rate is the only number that matters.
When a corporation replaces a human cashier with a camera and an algorithm, the least it can do is make sure the machine doesn't try to bankrupt the customer on the way out.
