For which two flavors is it essential to ask the customer if they want sugar-free or swirl?

The correct answer focuses on the two flavors, French Vanilla and Hazelnut, known for their popularity in coffee beverages. When preparing drinks that may include these flavors, it is standard practice to inquire whether customers prefer sugar-free options or the regular versions, especially considering the taste profile enhancements these flavors provide. French Vanilla and Hazelnut are often used in specialty drinks, making customers more likely to have specific preferences regarding sweetness.

Sugar-free versions of these flavors are available to accommodate dietary preferences or restrictions, which is why it’s vital to ask customers about their choices when preparing their drinks. By doing so, you ensure that the final product meets their expectations and dietary needs. This attention to detail and customer preferences is crucial in providing a satisfactory experience.
