Moments like this make me so glad I went to all the work of earning my MA in Info Resources & Lib Science:
Phone rings and my tech colleague answers the phone.
Caller: I'd like to speak to the reference librarian.
Transfers the call to me...
Hello, this is Amy at the info desk, how can I help you?
Caller: are you a reference librarian?
I need you to google something for me. What is the phone number of the North Mountain Mall?
Yeah, he definitely needed my expertise and that is something that my colleague could not have done.
