I remember getting sworn in back in the 70's. I kept my card till I retired in 2015. I also remember getting the dues receipts every month as well. Steward would put them in the turn in area, and you had to find yours if you wanted it.
I’ve told this story before
I used to tell the halfwit part timers if they’d take the receipt to Burge King they could get a free Whopper
One of them did got Allred assed and tried to get up in my face right before pcm with the whole squad standing there
We laughed about that for years
