That may be true, Guns, but it is neither the only nor the least likely case. If it's just one guy, it's less likely an issue of pay and more likely to be something else, like the player being used to games where you take everything that's not nailed down, or maybe he just thinks that's how the game is meant to be played, or it's something he sees as part and parcel to his character.
There is almost never just one possibility, and you don't have the grounds for that sort of certainty.
What sort of obstacles have been between him and the extra stuff?
