I'll cop some shit for this one, but coffee baristas.
you put some grounds in a machine, twiddle some nobs and pour milk in a wave pattern
edit: judging by the amount of downvotes ive either pissed off all the Bachelor of Arts grads working as baristas or all the coffee snobs who still think making coffee is some sort of art that can only be done by the most highly trained baristas. Yes, I also love coffee. No, making it is not some sort of complicated thing which is the point of this post (and topic of this thread), and no, I am not disparaging anyone working as a barista (unless they are an Arts grad, sorry) because a job is a job and all jobs deserve respect
