What type of drink qualifies for the combo discount?

Combo discounts are often designed to encourage customers to purchase larger drinks or meals as part of a combination offer, maximizing value for both the customer and the business. In this case, the requirement for a medium or larger drink ensures that the beverage is substantial enough to warrant a discount when paired with other food or drink items.

By specifying medium or larger drinks, the discount aims to enhance the customer's experience with a more fulfilling portion size, thereby increasing the likelihood of repeat purchases. Smaller drinks may not have the same perceived value or customer satisfaction, which is why they typically do not qualify for such discounts. This strategy could be rooted in market research indicating that customers prefer larger servings for combo offers, leading to increased sales and customer loyalty.
