Questions on the Laws of Theft

Hello, dear Rabbi. Once, a group of friends and I went to a fair where there was an event in the evening that cost 90 shekels. We arrived in the middle and asked the guards how much it cost to enter, and they mentioned a certain amount. After half an hour, we asked again, and the price dropped further... In short, it reached 30 shekels, and we still didn't want to pay. We sat next to the hall, and suddenly one of the girls found a side entrance. We sat on plastic chairs, and the girls claimed that it was a benefit without causing loss, and they wouldn't have paid anyway, but since the price kept dropping, it might have reached an amount they would have paid at the time we entered... I wanted to pay on the way out, but the guards left before the event ended. I wanted to ask if I am obligated to find the organizer and pay? And if so, do I need to pay for my friends as well? And how much? Another question: I went to someone who sells jewelry at home and accidentally returned home with a bracelet. I returned it to her, and she claims it broke while it was with me and wants the full price. I didn't do anything with the bracelet; it was with me for two days... And probably if I had bought it and it broke the next day, I would have received compensation... Do I need to pay? Thank you in advance and sorry for the length.

Hello 

A. 

You must pay the organizers the price as it was at the time you entered. 

There is no permission to enter an event for free, even if you know for sure that you would not have paid that amount. 

[This does not relate at all to the issue of 'this benefits and does not cause loss'].

B. 

If you did nothing and it broke, it is a defective bracelet, and in any case, you do not need to pay.
