Thanks. For me, I was in debate club in High School and that included basic rhetoric. In college I took an argumentation class as a non-engineering elective. The most useful thing this class taught (for me) is how to 'see' the argument, and as a consequence see how it is constructed. Throughout my career it has been especially useful in "political" situations at work. Not everyone argues in good faith, and being able to spot those who are not is valuable.
