In recent months, Starbucks has seen a massive surge in revenues from younger customers ordering elaborate, cold, customized coffees, like venti caramel crunch frappuccinos. These cold drinks now make up $70$ percent of Starbucks' revenues. So$-$called modifiers of these drinks $-$ think, a shot of espresso or three pumps of pumpkin sauce $-$ now account for more than $$1$ billion in sales each year on their own.

But the complexity of the drinks, along with order surges at certain times of the day, have made barista jobs more demanding and can sometimes result in delays. To help address that, the company unveiled a new cold beverage system that reduces the number of steps needed to make the drinks, as well as the need for employees to repeatedly bend down and dig into buckets for ice. In a demonstration of the system, two Starbicks employees showed that it took $35$ seconds to make a mocha frappuccino with whipped cream as opposed to $87$ seconds now.
