Poll: Soda Fountains -- Club Soda Ethics

I would tend to agree, but the point was made that in many cases you don't know the club soda button is an option until you get your cup, since it is not listed with an advertised cost. (Of course nothing stops you from going back to the counter and telling them that after the fact.)

I think it can get risky if you don’t know for sure. If the establishment has a drink nazi that will tackle you if you’re discovered to have helped yourself to a coke when you asked for a water, would anyone blame the drink nazi for assuming you helped yourself to a Sprite since the carbonation is easy to spot from across the room with a cheap pair of binoculars? It’s a risk I’m not willing to take.
