Case: Li Er picked up a dog while walking. He contacted the dog's owner Zhang San several times according to the number on the dog tag, but he couldn't get through. Li Er had to take the dog home. A week later, Zhang San contacted Li Er to return the dog. Li Er returned the dog as promised and asked Zhang San to pay 150 yuan for dog food and 500 yuan for remuneration. Zhang San refused: "the dog food fee should be paid, but why do you want to be paid?" Can Li Er ask for payment? In my case, it is not allowed. Article 979 of the Civil Code stipulates that if the administrator has no statutory or agreed obligations and manages the affairs of others in order to avoid losses to the interests of others, he may request the beneficiary to repay the necessary expenses incurred in managing the affairs; If the administrator suffers losses due to the management affairs, he may request the beneficiary to make appropriate compensation.
