What additional option do we always suggest adding to coffee orders?

The suggestion to add a turbo shot for an additional charge enhances the customer's coffee experience by increasing the caffeine content, which can be appealing to those looking for an extra energy boost. This option caters to customers who might require more alertness or simply prefer a stronger coffee flavor.

In a fast-paced environment like Dunkin', promoting an energy-boosting option is a strategic addition to their offerings, as it aligns well with the needs of customers who are often on the go and looking for a quick pick-me-up.

While extra milk, whipped cream, and cinnamon dusting can enhance the flavor or texture of the coffee, they do not contribute to the primary reason many customers choose coffee: to increase alertness and energy levels. Therefore, the turbo shot stands out as the recommended add-on that fits the brand's focus on providing high-quality coffee that meets customer needs for energy.
