Rock up 50mins before off blocks. The young keen F/O will have all the paperwork ready. The cabin crew will be chomping at the bit to get on board so you look at the F/O and say any issues? He says no and you tell the girls to get the hot water maker on.
Sign the flight plans and think of any slightly logical reason for some extra fuel. Walk out to the plane and let the F/O kick off so you have time to check the tech log and notams.
Do your 4 sectors and on the last the cabin crew are gone like a rat up a drain pipe. The F/O went slightly before that to file the paperwork and you retract the air stairs and walk back to your car.
Thats pretty much it in a nut shell.
Of course I could be talking complete fiction and fantasy so take all this with a pinch of salt.
