This is the best response yet, to your question.
The best advice I've seen on this came from long time road player Tom Ferry who made the rules before he started playing, and they included paying after each set and anybody can quit after a set if they want to. Takes all of the arguing out of it and doesn't ruin your future action.
I come down on the side of quitting when you are ahead if you want to but if you don't set the rules in advance you are partly responsible for the heat you will get from the loser. And, if you aren't getting payed after each set you are partly to blame for the air barrel at the end of the night.
