My Casino doesn't know right BS

Well, I was in progress of a game and one of the players at my table was questioning a play. Thus, I told him what the Basic Strategy play was. I don't remember what exact hand situation it was but I do remember that the pit boss came over and gave one of those little basic strategy cards to the player. Later after my push out I went and took a look at the card to see if it was right. To my surprise it was wrong. The game was 6deck, DA2, DAS, H17, and split aces once. The Basic Strategy card had missed plays like DD on A,8 vs 6 and A,7 vs 2. Also, 11, vs Ace.

I guess it's not all that important to get the right BS card. Just thought I'd share.
