Grand Casino near Shawnee, Oklahoma does not charge ante on any Blackjack table from on Mondays (starting at noon I think) through Thusday (Misnight?).
I gave up going there, I would drive an hr, and most times they would refuse to open a DD table, penetration is poor, and the pit wants to stare at your play if you bet more than $15 and play your cards with you. But they have no player tracking system at all, and do not want your name. There has been no antes for something like 6 months.
