Not a fan of WeWork, but there actually is something to this. We have two coffee makers in the break room at work, and there's always a line. If they brought in a barista who could work the machines, it's theoretically possible that you'd get better efficiency as there wouldn't be the dance of "who is next in line" or "sorry, gotta block the machine while I get sugar" or "I just want some hot water". I'd love to be able to point building management at some data that says that a barista costs $100/hour for 2 hours, but having them would unlock $1000/hour in lost productivity.
