Suppose Ruvein lends Shimon his car for thirty days, with the stipulation that if he returns it late he owes $100 (and no further details). Shimon returns it on day 15. On day 25 (of the thirty days), Shimon comes back and asks to borrow it again, saying "my thirty days aren't up".
- Is Ruvein obligated to lend the car a second time?
Suppose Ruvein lends it again, and Shimon returns it on day 40 (ten days after the end of the thirty).
- Does he owe the fine for returning on day 40, or do the thirty days start again and therefore it's like it was on day 15 and he'd be patur?
