And here in Canada, we refer to it as "pop." When I lived in the states for a year, I got so many confused looks when ordering.You reminded me how infuriating it was when I first moved here ages ago. In California we just called all soft drinks "soda" so then I moved out to Texas and it was like...
"May I take your order?"
"A number 6 with a coke please."
"What kind of coke?"
"What you mean what kind of coke?"
"You know, like Dr. Pepper, Root Beer, whatever."
"Just a coke."
"Oh a coke, why didn't you say so."
Used to it now, but every once in awhile you always get that place where you say you want a coke and they give you some other random soda because they thought you wanted them to surprise you.
We always called it "coke" when I was a kid in Texas. But that's because we actually drank Coca Cola. When I switched, I started calling it "soda" to differentiate what I was asking for from "coke"
