"Well," Jack says, looking at the ship, "If she doesn't need repairs, then all the better, but we should probably take a walk of the hull to make sure. I don't trust system scans all the time. Plus we'll need to restock fuel aaannd I tend to like to eat sometime during my weeks in hyperspace, so we'll restock food." He listens back and forth between Doc and Savi, and then to Bo before speaking up again, "Sorry, Bo, but keeping a ship fed is about ten times as costly as keeping any one of us fed. One share won't cut it. We'll be pulling from our own savings to buffer the ship's share before long."
He then turns to speak to the group as a whole, gesturing with his arms as he explains, "How 'bout this: We get paid; Ship gets repaired; What's left after that is considered our profit and a percentage - lets say half of the profit - goes to a group fund; We split the rest evenly."
"The group fund is in part for ship upgrades, because we need something besides those peashooters eventually, as well as for food and fuel, but also for job necessities. Maybe I set a precedent today, but I don't want to be in the habit of paying our docking bill every stop, so the group fund would pay for that, but also, what if a job demanded we each have, say, climbing gear? Do we just say, 'Oh, no, we can't do that,' or do we get the gear? If we get gear for each of us, does each of us pay independently? What if one of us..." Jack not-so-coincidentally happens to look in Avox' direction as he says this, "...Blew all of his credits on something stupid already; who foots the bill for him? What if a mission calls for us to have a speeder? Who's buying that? A group fund would make that easy, and would mean that whatever we get independently, while less, is ours, and we can spend it as we like without worrying about getting fed, or saving up enough for something that the next job needs."
