Badbeet, are you allowed to play blackjack at that casino without showing your players club card ? If there is a rule in place at this casino making showing your players club card mandatory before taking action then I have to wonder why you posed question in the first place (https://vegascasinotalk.com/forum/sh...01#post80201):
"Is there something in the players club rules stating that you must use your players card if you have one?"
Also, your original question, shown above, wasn't just restricted to blackjack but any felt game or machine game, but later morphed into blackjack only, chip redemption at a cashier's cage and any ID not just a player's club card. Quite the moving target.
Anyway, I will state again that I would like to see an explicit rule (web link I guess) about only getting to play machine or felt games if you show your player's club card (how they would enforce this on machine play is a whole other matter). I've never seen this rule so I am curious.
