How many scoops of flavor are added when a drink is ordered "extra sweet"?

When a drink is ordered "extra sweet," it typically means that an additional scoop of flavor is added to enhance the sweetness of the beverage. The standard preparation involves adding one scoop of flavor, so the option indicating one scoop is correct. This adjustment allows for a noticeable increase in sweetness without overwhelming the overall flavor profile of the drink.

In this context, the concept of "extra sweet" is implemented to provide customers with a tailored experience that suits their taste preferences, and one extra scoop is sufficient to achieve that balance.
