- " The counterman shook his head [at Marty's request for "something without any sugar"], left, and returned a moment later with a glass of water and cup of black coffee. Marty did not enjoy black coffee. / "Have you got any Sweet 'n' Low?" he asked, then quickly added, "Or something like it?" / "Tell me what Sweet 'n' Low is," the counterman said, forcing patience into his voice. / "It's an artificial sugar substitute with no calories," Marty said. / "We don't have anything like that." / The Middle Ages, Marty thought.

Sweet 'n' Low was an artificial sweetener.
Marty then asked Lou if he had any Sweet 'n' Low, or something like it, which Lou had never heard of. When Marty explained what Sweet 'n' Low was, Lou said he didn't have anything like Marty had described.
Behind the scenes
- Although the actual product is stylised as Sweet'N Low, it is spelled in the novelization as Sweet 'n' Low (see Quote above). The novelization's spelling has therefore been adopted here.
- It is only natural that Lou has never heard of Sweet 'n' Low, as the product would not be introduced until 1957.
