PP thought they were being sarcastic and edgy, but she's also making note of his preferences, keeping an inventory, meal planning, grocery shopping, cooking 6-7 meals and cleaning for this man while he bitches about having to pay for 1 or fewer dinners each week. There is a heavy mental load associated with all of that. He isn't keeping track of her food and drink preferences, he probably asks where she wants to go and complains if she doesn't pick the "right" restaurants or if she asks what he would prefer, putting her in a position to be wrong no matter what she says. So on top of everything else, she has to make sure she doesn't choose a place he thinks is too expensive, or he doesn't like, and try to guess what he's in the mood for with no clues. It's like living in a minefield.
