A guest arrived early one morning at the Hotel Ohio. Clemens, a person in the hotel office who appeared to be in charge, walked behind the counter, registered the guest, gave him a key, and took him to his room. The guest also checked valuables (a diamond pin and money) with Clemens, who signed a receipt on behalf of the hotel. Clemens in fact was a roomer at the hotel, not an employee, and had no authority to act on behalf of the hotel. When Clemens absconded with the valuables, the guest sued the hotel. Is the hotel liable? Why?*
