The part nobody talks about is how the client knew before you did. Some random guy from Cleveland sits down and just quietly tells you your fade is off, and that means he has been watching cuts for years and clocked yours as wrong from the chair. That is the scary thing. The people in your chair know. They just do not say anything because they do not want to be rude or hurt your feelings. So you go six years thinking you are solid while half your clients are just tolerating it. One honest dude from out of town finally says something and that is how you find out.
