> One poster above said a large soda in the USA is almost one litre!
There are two sizes of single-serving sodas sold commercially in the US.
A small one, a can, is 12 oz, 355 mL.
A large one is 20 oz, 591 mL.
To buy a 32-ounce soda, you'd have to do something very strange.
(There is another common commercial size, the two liter bottle of exactly 2000 mL. Those aren't intended to be bought and drunk; they're intended to be bought, taken home, and stored in your refrigerator over time.)
A gas station? No, they'd be selling prepackaged sodas in the 20-oz size.
You might be able to do it at a 7-11, since they sell empty cups that you're meant to fill with a slurpee. I don't know if they also have soda fountains to fill those cups.
