Your barista is a robot. Should it be friendly?

The cold, steely arm of Fernando the Barista swirled the foam of my matcha latte, set it down gently and waved goodbye from inside a glass case. Where you can get robot pizza and robot salad, and now, a robot matcha. There were humans inside the small coffee shop on Market Street, but only some of them ordered drinks. Some of them came in just to gawk at Fernando: The machine was sleek and white, like an Apple product, and its glass enclosure made it seem like a small animal on display. "They all have'it' pronouns," said Sam Blum, Cafe X's community manager.
