My friend picked up a trempist (hitchhiker) who did not put on his seatbelt. Police pulled the car over and gave a ticket to the driver (not the passenger) for driving with someone not buckled. Should the passenger reimburse my friend?
I was at a coffee shop, and an ostensibly religious Jew (Reuven) left intentionally without paying. I heard the angry reaction of the proprietor (Shimon) and decided to pay instead of Reuven, hoping to reduce the chillul Hashem. Did my payment exempt Reuven? What about paying kefel (double payment for covert theft)? How did it affect Reuven’s teshuva process? Also, were the berachot Reuven made on the food l’vatala when it turns out retroactively the food was stolen?
