Huh, interesting. I suppose that works the same as with soda - you say soda and then clarify what brand - but it's weird because with Coke, that's one of the possible brands you could want, especially since up here no one everrrr says Coca-cola. That's what makes it different from Xerox/Band-aid/Kleenex - you don't have to ask someone for a Kleenex and then specify that no, I wanted the Puffs instead. I dunno.

And I've never heard of saying co-cola, that's so interesting! Language is funny.
