You’re right, of course, about DIY coffee for pennies a cup. But I once asked a “barista” at my local Starbucks what percentage of customers order plain ol’ coffee. Her answer? Ten percent! The other 90% are getting those ridiculous sugar- and syrup- and whipped-cream-filled concoctions! Can’t really make those at home.
YOU can buy Caramel syrup & use it at home.
