"Do they have enough black soda pop?"
Translation:Onko heillä tarpeeksi mustaa limonadia?
True. In real life, you'd probably call it kokista or kokakolaa, regardless of the actual brand.
I heard recently that restaurants are actually more likely here to have Pepsi on tap than Coca-Cola. If you order coke, some will ask you if Pepsi is OK, others will just serve you whatever black fizzy drink they have. So people who are particular about this have to ask when ordering. Apparently, the "default" on tap in most of the world is Coke, but not here.
