When your grocery store's price tag system decides to have a full existential crisis and starts speaking in JavaScript data types. That price tag is literally displaying "£NaN" which is what happens when some poor soul's code tries to do math with something that absolutely, categorically, REFUSES to be a number. Someone's database query probably returned undefined, null, or maybe just the screams of a thousand developers who forgot to validate their inputs. The system looked at whatever value it got, tried to calculate the price, and just gave up on life entirely. "Not a Number? Cool cool cool, I'll just print that directly on the shelf for customers to see. What could go wrong?" Meanwhile shoppers are standing there wondering if they need to pay in existential dread or JavaScript errors. The real kicker? It still shows £3.69 right next to it, so the system KNEW the price but chose chaos anyway.
