There are some things you should never do in a coffee shop. You may think your behavior is totally normal, but you might be royally pissing off your barista. Who cares, you say? Well, not only will your baristas secretly dread seeing you, you may actually be slowing down the pace of the cafe for other patrons. So many people (most of them good people) are guilty of such bad etiquette that I thought I’d list some items here for all to see.
