Yes, this seems unimpeachable. The missing piece is, rational at what margin? Once you are home, it is not rational at the margin to pay the $100 you promised.

This assumes no one can ever find out you didn't pay, as well. In general, though, it seems better to assume everything will eventually be found out by everyone. This seems like enough, by itself, to keep promises and avoid most lies.

Right. The question of course is, "better" for what purpose? Which model is better depends on what you're trying to figure out.
