Let’s say you’re using an Alexa skill that seeks out nearby karaoke nights in your city. It finds one at a cozy little bar across town. “Should I go ahead and order you an Uber?” Alexa asks. You’re still in the karaoke-finding skill, but that doesn’t matter. You say yes, Alexa orders the Uber, and you start warming up for a rousing rendition of Welcome to the Jungle while you wait for your car to arrive.
