Sound the alarm: There's a crisis in Starbucks land. Customers nationwide have been devastated by a shortage of Pumpkin Spice Lattes, an autumn-only favorite. "My world almost ended this morning when the local Starbucks told me they were out of Pumpkin Spice Latte," tweeted one fan. Another store visitor says he "just left, depressed." Starbucks has hyped up the drink with campaigns including a Haiku contest, and this year, demand has soared, the Wall Street Journal reports.
