Please be advised:
If you call me after 3 p.m. and say, "Good morning," I will hang up on you. Especially if you continue with "I'd like to speak to Miss Albert Sanders."
If you call me and say, "May I speak to the person in charge of..." no matter what you say next, I will hang up on you.
If you call me and say, "Hello Mr. Audrey Carter" I will hang up on you.
If you pronounce Graham "Gray Ham", if you say you are with Qwest, if you say you just have a short survey, if there is a long pause before you begin talking, or if you ask who maintenances my copy machine, believe me when I say that I will definitely hang up on you.
