Me: Oooo new iced coffee flavors. I think I’ll have an Iced Brown Sugar Oat Milk Shaken Espresso please. Startbuck’s drive thru speaker: “There’s a nationwide shortage of oat milk… ….and brown sugar.” Me: What on earth?? Could this be true and if so, why?!! So I ordered the Iced Chocolate Almond Milk Shaken Espresso instead. It was good, but no where near as tasty as the Iced Brown Sugar Oat Milk Shaken Espresso.
