As a fellow ex-help desk guy :tm:. I just want to say that A) I feel you but also B) the very fact that you know no one reads manuals should be an indication that expecting them to is a flaw. Instead most people generally do better with hands on coaching. Idk about your job, but back when I was working help desk I got way better results when I let people just be people and patiently guided them through the steps. Most of them catch on eventually
