nick and gloria are banned from participating in poker games at the dugout because gloria has a really, really good grip of poker math and is a sore winner, and because during a game nick unplugged the nerves of his face and slapped them down on the table and it freaked people the hell out, and any game with the both of them is a total shitshow because they want to beat other people but they really want to beat each other
nick has a pretty strong no-gambling policy because he's acutely aware his tumultuous personal life and many many demons prime him to be the kind of guy who'd lose a lot more than just money to games of chance, up until gloria sits down at the table, at which point the urge to best her competitively wins out and he starts throwing caps down as fast as he's able
