What are the secondary syrup pump amounts for a small, medium, large, and XL?

The correct answer reflects the standard practice for the amount of secondary syrup pumps used in beverages across different sizes at Black Rock Coffee Bar. For a small cup, using one pump of syrup effectively enhances the flavor without overpowering the coffee's natural taste. As the cup size increases, the amount of syrup also increases incrementally, with two pumps for a medium, three pumps for a large, and four pumps for an extra-large. This approach ensures that each beverage maintains a balanced flavor profile consistent with customer expectations while allowing for a personalized touch. It also aligns with the company's guidelines on creating a harmonious blend of flavors in their drinks.
