Rock would cook stuff and Bridge Four would have to smuggle it in with their pockets. Kelsier would approve, but he'd find a way to steal stuff for himself. Vin would have a ton of cash on her so she'd buy stuff for a ton of people. Dalinar would want to pay for himself though. Nightblood would insist upon milk duds because why not and Shallan would say she only got a water, but in reality, it would be a lemonade. Adolin would buy way too much chocolate and share with Renarin.
