Perhaps there could be a limit of the gold sent to an adventurer. I did several scoutings of regions around different areas of the realm for my general which was done thinking I was to be paid since he was unaware that I couldn't receive gold from him, which gives me no incentive to do if I plan on staying an adventurer since I don't get gold and my advy I plan on keeping an advy so it seems to me there is no reason to please nobles, obviously not to anger so they don't arrest you but there is no actual reason to please from what I see.
The not beating up part is pretty important. Or arresting you and having you executed.
He might be able to use a guild to pay you, if you are both members and you have the ability to withdraw gold from the guild treasury.
