That goes along with:
Them: HI I need to speak to Bob
Me: Sure, I have 3 here in the office; which one would you like?
Them: Bob in X Dept
Me: Well this is X Dept are you looking for Bob A, Bob B or Bob C
Them: (getting angry) I just want to talk to BOB!
Me: Okay, can I ask what this is in regards to? (thinking I can figure it out this way)
Them: NO! It's personal! Just transfer me to Bob
Me: Well can I have your name so I can see if Bob is available to take your call (I'll hunt each down if I have to!)
Them: (really angry now) NO! JUST GET ME TO BOB! ARE YOU THIS INCOMPETENT?
Me: One moment please... (grab first Bob I see) are you expecting a personal call from someone who doesn't know which Bob you are. If not do you know which one of you it is?
No okay on to the second Bob.
<swearing to myself NEVER to name my kid BOB! I hear Claudius is a nice name)
