1. If someone works at fruits farm, is he allowed to eat those fruits on job site without permission of owner? Or he must seek permission for eating those fruits?

2. For example If owner of the strawberry farm himself personally offers him to eat the strawberry, but he refuses owner’s offer saying I don’t like to eat strawberry, but later on he eats one strawberry. Does he still need to seek permission or tell him about strawberry he ate, Or does he consider his offer as he granted the permission of eating?

If he is not the owner and does not have direct permission he should not eat. In the second instance, he needs to ask the owner if it’s ok to eat sometimes otherwise just because he was offered and he eats later is not sufficient without permission
