Supermarket ambience is a staple of soundboard and editing libraries because grocery stores are such a common everyday setting in sketches, vlogs and animations. Rather than coming from one famous film or meme, this kind of clip is valued as a reusable piece of background audio that instantly tells viewers where a scene takes place. Creators search for it when they need a believable store atmosphere without recording one themselves, and its short length makes it easy to loop, layer under voices or drop briefly between jokes.
