Bava Kamma 116 - Saving Your Friend's Honey by Losing Your Wine (Torts)

One was with a barrel of wine, the other with a jug of honey, and the barrel of honey cracked. If the wine owner poured out his wine and saved the honey, he received only the laborer's fee. If he said, "I will save your honey, but you must pay me for my wine," - the other is obligated to pay.

But compare this to the one fleeing from a prison, who can promise the ferryman an inordinate amount for taking him over the river and then say, "Just kidding," and pay only the fair?  - That's different because the ferryman loses only his time.
