Fast travel that uses up food and stops on the road when the food runs out

Jumping between camps should not be free in a game about hunger. The cost has to follow the road that is actually taken, round in the right direction, and leave the player somewhere sensible when the bag runs dry halfway. Here is a rule that does that.

Why this works

Players trust a cost they can learn. Charging by the real road, rounding up so no trip is free, and stopping where the food ends shows them exactly what a journey costs, instead of a refusal that teaches nothing and invites guessing.

When not to use it

Do not use it when the road is dangerous enough that stopping halfway could trap or kill the player with no fair warning, or when the story is about a calm trip. Then refuse before the start, and say how much is missing.
