Bigend has a way of injecting these questions into conversations that he's grown tired of. Caltrops thrown down on the conversational highway; you can swerve or you can hit them, blow your tires, hope you'll keep going on the rims. He's been doing it through dinner and their pre-dinner drinks, and Cayce assumes he does it because he's the boss, and perhaps because he really does bore easily. It's like watching someone restlessly change channels, no more mercy to it than that.
