Breakdown of sales with & without syrup

[spark]

I am looking to see what existing coffee shops sales are, percentage wise, of drinks made with vs. without syrups? For example, only 20% of all drinks (bean based and italian sodas) made with syrup. As I don't like syrups in drinks other than italian sodes, I have no clue what this number should be.

Also, what are your top syrup flavors?

Thanks
Neil
