I called AT&T yesterday to fix a billing error. I talked to a woman sales rep–a black woman, by the way she talked, if I may be stereotypical (and possibly wrong). She was very thorough, and got things straightened out.
I concluded, “Thank you. You’ve been very helpful and very professional.”
She immediately perked up, as if she hadn’t been complimented in years. Her friendly tone shifted up a couple notches as she wished me a great day.
Be nice to the customer service people on the other end of the line. They get chewed out by angry callers all day long for stuff they didn’t do. Give them a moment of satisfaction. Everyone needs that.
