I made a 2-day trip back to USA, and I had a layover in Dallas Fort Worth. By chance, I ordered a soft drink, and the bloke selling it to me called it a "fountain drink", which I hadnt heard outside of USA, since fountain drink refers to a drink that you can get out of a soft drink fountain. What do people outside USA call this since I see this soft drink fountain in literally every country? In Australia, our Subways and cinemas have it accessible on our side, though I had never seen anyone take a free refill from it even though there lacks any signage saying refill are prohibited.

In USA, we usually call it a soda fountain despite not all of the soft drinks are sodas, so really we should be calling it a soft drink fountain as we use the term soft drink, and we only use the term "soda" for specific soft drinks, not as a synonym for any soft drink. We would never call "lemon squash" or "fruit punch" a soda even though both are soft drinks to us, though I have never heard people in USA use the term "squash" for a drink. What would "squash" in USA be called?

Anyways, what are fountain drinks called outside of USA? In other words, how would someone outside USA refer to a drink that is specifically meant for a soft drink fountain?
