The voice comes from Walmart self-checkout machines, where an automated announcement guides shoppers through paying and then thanks them for shopping at Walmart. Because the wording is so specific and instantly recognisable to American shoppers, the short clip travelled from in-store recordings to meme soundboards and short-form videos. Creators reuse it whenever a scene involves paying, queuing, or a purchase that goes wrong, and its deadpan, corporate politeness makes even a simple shopping joke feel more awkward and relatable.
