Every so often, we have a customer who tries to push the envelope. Because they are having a bad day, or a bad week, or they just feel like it. I remember one instance where one of my customer service reps got abused by a customer. The thing was that he worked for our auditor, and I don’t think he knew they were our auditing firm as well. And it wasn’t just one of those stern, I-am-not-happy-with-you calls. It was a call laced with four letter words, references to my rep’s mental capabilities, and the origin of their birth. I called our finance department, and the finance department called their account manager, after which my rep got a formal excuse, and we never heard from that person again.
