Dinim on Damages

The following stories and the rulings that follow are based on the Chashukei Chemed and Pninei Halacha on Bava Kama. They are not intended to be relied on for practical halacha.
1. Shimshon had a venomous snake as a pet. One day, it managed to escape its cage. Levi was walking by and was bitten by the snake. Levi was rushed to the hospital and was treated with anti-venom. While being treated, the doctors discovered that Levi had a rare and usually fatal condition. The snake’s venom cured him! Levi called Shimshon to express his profound gratitude for saving his life from his hitherto unknown condition. Before he hung up, Levi also casually mentioned that he expects payment from Shimshon for his pain, suffering, and doctor bills. Shimshon said, “Really?!? I saved your life!”
2. A hundred and fifty years ago, Boruch owned a liquor store in Hungary. The authorities there had a strict law regarding selling imported liquor. Chaim purchased a large quantity of liquor for his simcha. At the simcha, Chaim tasted the liquor, and it was awful. The next day, in a fit of rage, he smashed a whole section of bottles in Boruch’s store. Later that day, government inspectors made a surprise appearance at the store. They did not find even one bottle of contraband liquor because Chaim smashed them all. Boruch sent a message to Chaim thanking him profusely for saving him from certain imprisonment, confiscation of his liquor, and steep fines. At the end of the message, he also included an itemized bill so that Chaim could reimburse him for the bottles that he had smashed. Was Boruch correct in demanding payment?
