Coffee made by robots because . . . ?

The San Francisco Bay Area is rightly famous for its tech industry. Apple, Google, Facebook, Twitter, Uber etc. . . . and those are just the consumer brands. There are also business-to-business brands like Oracle and Salesforce. 

Everyone has their favorite phone, tablet, laptop, app, website, and so on. Everyone also has their nominee for dubious achievement by a tech company. Mine is the insulated cup with a built-in USB port so you can plug it into your computer and it can tell you if you're drinking enough water. 

And then there's this robotic coffeebar. It's exactly what it sounds like. You can stroll into this place, tap the app on your phone that orders your drink and pays for it, and watch as a robot makes your latte, mocha, or whatever. 

I've been trying to think of possible advantages for the customer.
1) Assures him he is cool.
2) Liberates him from having to deal with a barista who says things like, "How's your day going so far?"
3) . . . honestly, that's all I can come up with.

For the owner, I assume the robot is cheaper than employees.
