My best DH stories are from my sub-par regional.

I’m sitting Airport Reserve at an airport with about a dozen terminals.
Crew Scheduling calls. “How soon can you get to gate K79?”
Me - ”I’m in the crew room, I dunno, maybe 15 minutes?”
”OK, they are boarding PIT right now. I need you to DH there and then operate a flight to somewhere... I will list you on the flight by the time you get there”
Me - ”OK”

So I go straight to the gate, work my way up to the agent, and they say “I’m not putting you on this flight. It’s full.”
Me - “OK”
I call crew scheduling, wait on hold while they complete boarding, and then explain the situation.
They say ”You have to talk your way onto that flight or the next flight will cancel!”
Me - ”They don’t even have my reservation.”
CS - “I can’t list you because we’re too close to departure!”
Me - “We’ll, the door is closed and I’m watching the plane push back right now.”
CS - “Dont leave the gate area. I’m gonna make some phone calls to get that plane back.”
I proceeded to go back to the crew room to sit out the rest of my 10 hour shift.

Anybody want to wager on if my regional crew scheduler got that mainline plane to come back to the gate?
