Hey! Shy First Officers out there:

1. JS: "Hi, I'm Chuck Hoover, from ZV airlines, may I please have a ride home?"
2. CAPT: "Hi, I'm Bob Yeager."
3. -js extends credentials towards capt's hand
4. -capt takes credentials
5. -capt looks over credentials

Sometime in between Number 3 and 5 above, extend your hand to the jumpseater and say "Hi, I'm Jeanna Wagstaff."

It works.....
