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 Starbucks employees showed that it took

$35$ seconds to make a mocha frappuccino with whipped cream as opposed to $87$ seconds now.
