re: Companies who at some point fired workers for not getting Covid shot

I'm one of 3 boys that came up on a hog farm in the middle of nowhere Kansas.
My wife (no pics) is from California. We made a trip out to L.A. for a funeral during the height of covid.
We headed into a high class seafood joint per the wife's request. The Placard outside said vaccine card required.
Walked in and the man at the door asked if I had my card handy. I smiled and said "what do you think?"
His response- "right this way sir."
