So tomorrow I have a customer comming who is starting to make me nervous. He is one of my mom's co-workers, and just bought an '06 Chevy Malibu Maxx LTZ that he wants protected. Yesterday, my mom comes home with a stack of papers he wanted her to give me. I look, and find that he copied the "Appearance Care" section out of his owners' manual, thinking that "his car has special paint" that he wants to be sure I use the "approved stuff GM recommends" on it. In other words, GM's own chemicals/supplies, and its own recommended procedure. I almost asked her to go back and tell him to "fuck off" but I decided I'll take the job anyway, and just not tell him what I'm using on the car. I just can't believe he would insult me like he did, when he KNOWS I'm a professional. Right now, I'm just worried that he's going to complain about the job no matter what I do... and that he'll still try to tell me what I should use on his car. Anybody have thoughts on how I should handle this customer? I just don't want to end up looking at him and saying "If you know so much, go do it yourself, moron."
