That doesn’t help. You can already buy large bottles of soda, or multiple bottles of soda, for your own use at home.
The question is, could a restaurant sell you the ingredients, and have a machine in the store that they could use to mix their own soda. Except that is silly, because the law allows refills. So you could already get a 16-ounce cup, and they could charge ten cents a refill, and 1 buck for the cup (if the law doesn’t allow free refills).
The stores don’t mind so much, because it gives them an excuse not to sell a pitcher of soda, which makes less money for them than the individual cups.
Of course, every theme park I go to, I have a refillable cup that is more than 16 ounces, and get cheap refills. Fortunately, nobody is stupid enough to build a theme park in downtown new york city.
I wonder if Coney Island is covered under the law?
