Wait for the beep.

I try not to be too snarky, but this is my next out-of-office message:

"Hi, you’ve reached the desk of Michael Martineck.  I’m out of the office, so please leave a message.  If this is an emergency, please call Jim.  He’s not in the Advertising Department.  He did two combat tours in Iraq and will tell you what a real emergency is."

A first-responder in the advertising world is someone who gets to the meeting ahead of everyone else to get the pick of the muffins. 

End of mini-rant.
