A work related pet peeve of mine is when someone will call after hours and leave a message like, "Hi Pam, this is John. I spoke with you a couple of weeks ago about my application. Please call me back." No last name, no number, no nothing to distinguish him from the 6,000 other Johns in our system. I call LOTS of people everyday, and then pass the file on, I don't remember you John!!!! So now my only option is to wait for John to call back, and most likely, when he does, he is going to be pissed that I never called him back!
