The only staff traveller issues I've had are the ones who don't thank the CN for the J/S. Yep, last sentence in the OP is the clue.
You know gracious folks are often blocked by the Cabin Crew from saying thanks to the Capt for the J/S? And you can't be sure if a message of thanks is passed on either.
I approved dozens of CX staff for the J/S last month and although I wasn't upset nobody said thanks I found it kind of strange. Looked back a few days ago and a couple of F/A's bearing gifts were being told I was too busy.
This place is getting weirder by the day.
