I admit I try and wring any little piece of information out of whoever answers the phone. I try to be nice about it, like anything I get will be gravy. So many calls go "Hi. I'm so-and-so. Here's my problem and so-and-so said that you could help. Are you the right person? If not, can you point me in the right direction?"
In the new job I have tons more of that to do. Not only am I still feeling my way around, but information is obscurely held here, and that "if not, then who?" question is scarily revealing.
So I don't take umbrage with people who ask what I can't answer--until they get huffy. Which happened a lot in my last job--somewhere in the phone IVR system my number came up for customer support. The company was about 15 divisions strong and I never quite worked out which one of them people thought they were talking to. But man, did I get cussed out for saying that I was in IT and couldn't help them resolve account issues--and to top it off, no I can't transfer them anywhere, because I don't know where they came from, and we don't know any of the customer-facing phone numbers anyway.
Man, that English breakfast latte was good. My appetite is inching back into existence.
