Isn't ice 32 degrees?

I see this little scrolling sign at work every day - truth in advertising? How can the beverage be 'ice-cold' at 37 degrees Fahrenheit when ice, by its very nature, must be at 32 degrees or below?

Truth be told, if the produce were delivered as advertised, it may present as a block of ice (unless there are impurities which raise the freezing point, like salt) which most customers might find objectionable)
