"Clerks get into the damnedest wrangles--which is the way they help me."

There's a part of me that is angry. Not in the sense of, "Gee, George is an angry guy!" I mean, anyone who's been with me five minutes, five years, whatever, they would tell you they've rarely seen me in a moment of anger. Yes, I can become highly irritated in a line that's moving slowly, or with a clerk who's incompetent. But I don't yell. I don't get rude. I am clear about what I expect. In a store, my mother always told me, "Ask for the manager immediately. It changes the tone of the conversation."
