My brother happened to be near AC and posted the following report from Ocean Casino in AC:

All croupiers wear face shields. The blackjack tables have no barriers or distancing (people sitting next to each other) At roulette and craps table, a plastic barrier around the game table. The craps table has additional barriers between each player. Players have about 12 inches under barriers to place bets.

At slots, they took chairs out to keep distancing.
