The Talis Exchange

A laundry returned the correct quantity of items that had been brought in originally; however, the customer, Reuvein, later realized that one sheet was not his. Someone attended a wedding with one coat and, mistakenly, returned with a different one. The concern in all these situations is that one is using someone else’s property without permission. This is called sho’el shelo midaas, borrowing without the owner’s knowledge, which is usually halachically equivalent to stealing (Bava Metzia 41a; 43b)!.
