California 'special relationship' doctrine recognizes that certain relationships impose an affirmative duty to protect from third-party harm. Which is a recognized special relationship most relevant to security work?

Explanation

California recognizes special relationships that create affirmative duties to protect another from third-party harm. The business-invitee relationship is most relevant for security: owners and their agents owe invitees a duty of reasonable care, including foreseeable third-party criminal conduct, with scope shaped by Ann M. v. Pacific Plaza Shopping Center (1993) 6 Cal.4th 666 and Delgado. Other recognized special relationships include innkeeper-guest, common carrier-passenger, school-student, and therapist-patient (Tarasoff duty to warn). Strangers in public (a), casual social contacts (b), and uncontacted pedestrians (c) lack the special-relationship trigger.
