What's the Name of That Book??? discussion

Read this in early or mid 80's. Utterly ridiculous self help book wherein the author suggests people never take no for an answer. I remember one chapter about freaking out in retail shops to get what you want. The author keeps using the phrase , "Remember, a clerk is a jerk!"

Pulling Your Own Strings by Wayne W. Dyer? It has this:
“I'm really sorry, but you'll have to send us a letter.” Or, “Stand in that line.” “Come back next week." “Just plain go away.” Perhaps the best way to deal with the clerks of the world is always to remember these five words: A CLERK IS A JERK! No, not the person behind the role of clerk; he or she is intrinsically a wonderful, unique, important person, who becomes jerky when turned into a policy enforcer paid to victimize you. Avoid clerks, and deal with people who can be of service to you.

Wow, thanks. That's the one. Been bugging for weeks now. Thanks again!
