Just sell 16oz of beverage in a 40oz cup with a small bag of ice.

Same thing they were selling before, just some assembly required.

Or sell 16/32/40oz cups, with free ice/drinks. Isn't that what most places do anyway?

Or you could also just post a sign next to the soda fountain: Do Not Fill cup over 16oz. Then it's the customers' faults.
