Why do people that hang out at coffee shops think they are so sophisticated?

My opinion exactly. And the names they call the drinks are impossible. You need to take a course to understand them all. The coffee companies and shops are onto something. We all like to have something about our own selves that are with it. We are like the guy next to us. We are in the same wave lenghth. We like to appear to know what is happening in the coffee world. How lame is that.
