So...here's a random question...
There are parts of the U.S. where sweetened, carbonated beverages are referred to as "soda" and parts where they are referred to as "pop." I remember the first time (in 1990) I heard someone refer to soda as "pop." It was this rather stereotypically blond girl who was hired as a receptionist at my office. She was, if I remember, from Colorado. I thought it was REALLY odd, because I thought of "pop" as a bit of an archaic term from the 1950s (ish).
Anyway...more recently, I have learned that there are parts of the country where any sweetened, carbonated beverage is referred to as "a Coke" (perhaps without the upper-case "c"). So my question is, if you're in such a place and you want a Coke (aka Coca-Cola), how do you order it? I assume that, if you say, "I'd like a Coke, please," you'll get asked in response, "what kind?" or something like that. Do you have to say, "I'd like a Coke - specifically, I'd like a Coca-Cola brand cola drink"?
