The stuff shouldn't be called "lemonade", period. "Hard lemonade" gives the impression that the beverage's alcohol is derived from natural fermentation of lemonade in the same fashion that hard cider is derived from table cider. It's not. The stuff is nothing but a cocktail make of lemon juce, carbonated water, and vodka.

I think the guy should file suit against the ballpark for having sold the stuff without making it perfectly clear that it is an alcoholic beverage.
