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.
What other social interactions are needed more than: "One flat white to go, please", and "Thank you"? Asking genuinely, because I don't know what else I can say.
I usually make coffee at home, but the baristas are remarkably stable in my area. When I do go to a coffee shop (there are 2-3 that I might go to) there’s a good chance I’ll recognize the barista and that they’ll also remember me. In one such case I’ve been seeing the same one for close to a decade, and we always chat for a bit.
I think most baristas who do it for more than a year or two learn to not primarily be a coffee factory but first to make a positive impact on the people they see. The coffee is something that can be made consistent (and in a way, boring) through practice, but personal connection, especially when it is genuine, has a real draw.
Lots of things. “Could I have some sugar, please; two frappy mochachos? one with almond milk; can you explain what all these options are, please; what the hell is mushroom powder?” In today’s coffee shops this can lead to hours of complex social interaction at the counter, enriching our lives and ultimately extending our lifespans. — sorry, couldn’t resist. In seriousness, I actually find this conversation interesting. Some coffee shops do have quite a social culture around them, though I think they’re outliers on whole. Here in Spain it’s a mix, but in some it is like everyone’s friends with the barista.
