Sabrina was hospitalized with severe gastrointestinal pain and placed in an intensive care unit. Her doctor, Pierre Delecto, told the hospital personnel to order around-the-clock nursing care for Sabrina. At the hospital's request, a nursing firm, AT-ONE Services, LLC, provided two weeks of in-hospital care and, after Sabrina was sent home, an additional two weeks of at-home care. During the at-home period of care, Sabrina was fully aware that she was receiving the benefit of the nursing services. AT-ONE Services, LLC later billed Sabrina for $10,000 for the nursing care, but Sabrina refused to pay on the ground that she had never contracted for the services, either orally or in writing. In view of the facts that no express contract was ever formed, can AT-ONE Services, LLC recover the $10,000 from Sabrina? If so, under what legal theory?

Can someone help on this?
