Which suggestion would be appropriate for upselling a tall Biggby Best?

The suggestion to add flavor and propose the americano is an effective upselling strategy because it enhances the customer's experience by personalizing their drink. By suggesting an americano, the barista introduces a popular choice that can be tailored to individual taste preferences, augmenting the basic offering of a tall Biggby Best.

This option not only encourages the customer to try a different beverage that pairs well with their current choice, but it also provides an opportunity to introduce additional flavor options, which can deepen customer satisfaction and drive an increase in sales. Adding flavor to the americano can further entice the customer, creating a more unique and pleasurable drinking experience.

In contrast, other suggestions may not effectively enhance the original drink or could limit the customer's enjoyment. For example, upsizing and reducing sugar could change the fundamental nature of the drink, potentially making it less appealing. Similarly, adding extra foam and decreasing temperature or removing whipped cream and adding caramel might not suit every customer's preference, leading them away from selecting the Biggby Best altogether. The approach of recommending the americano, paired with flavor, leans into customization and enhances the likelihood of customer satisfaction and repeat business.
