This audio is known online as La CB12 or La CB12 s'il vous plaît, and it circulates mainly as a French meme quote rather than a clearly documented film or TV clip. The version here is associated with the name Anyme in user uploads and searches. It spread because the dialogue sounds oddly specific and increasingly ridiculous, which makes it easy to reuse in short edits, subtitle memes and customer service jokes. Its staying power comes from the quotable delivery and the everyday fast-food setting turning into nonsense.
