Is it possible that the coffee drinkers have more social interaction with the barista and others? It's unclear from the paper if they eliminated the confounding factors around coffee drinking.

Coffee can also be a very social thing right? In Denmark for example (Australia slightly less so) there are lots of social “coffee breaks” at work.
