What is the instruction for extra ice?

In the context of beverage preparation, the instruction for extra ice typically means to decrease the liquid volume in order to create more space for ice, which will not only chill the drink further but also maintain balance in flavor. Choosing to take away 2 oz and adding a full cup of ice is a method to ensure the drink remains enjoyable despite the increased dilution that comes from adding more ice. The net effect is often a cooler drink that doesn't compromise too much on flavor.

Other options do not align with standard practices for adding extra ice. For example, adding 1 oz or 3 oz of ice without adjusting the liquid volume could lead to an overly diluted drink. Removing all ice would eliminate the benefit of chilling the beverage, which is counterproductive when the aim is to provide extra ice.
