Final answer:
Historically, innkeepers were subject to the duty to provide accommodations and they were strictly liable for guest's property, representing key principles of old common law concerning their profession.
Step-by-step explanation:
Two examples of old common law specifically applicable to innkeepers are the duty to provide accommodations to travelers and the liability for guest's property.
The first common law duty, duty to provide accommodations, mandated that innkeepers must offer lodging to travelers, so long as they have room and the travelers are able to pay and behave properly. This law originated from the public interest in ensuring that travelers could find safe shelter.
The second common law duty involves an innkeeper's liability. Historically, innkeepers were held to a very high standard of care concerning the personal property of their guests. They could be held strictly liable for the loss or damage of guest property unless the loss was caused by an act of God, a public enemy, the guest himself, or by an inherent defect in the property.
