What does a "+" signify after a flavor abbreviation?

The answer indicates that the "+" sign after a flavor abbreviation represents an extra amount of syrup added to the beverage. In many beverage systems, particularly in coffee shops and cafes, this notation is used to specify that the standard amount of syrup should be increased to enhance the flavor profile of the drink. By indicating extra syrup, it communicates to the barista that the customer prefers a sweeter or more pronounced flavor, which can significantly impact the taste experience of the beverage.

Understanding this notation is essential for accurately preparing drinks according to customer preferences and ensuring satisfaction with the beverage's flavor intensity.
