The correct answer is Store proprietor. The Store proprietor has the strongest reasonable expectation of privacy regarding the premises and daily operations.

The Store proprietor owns or controls the business premises and sets rules for access and operation. Ownership and control create the primary interest in confidentiality for inventory, business records, layout, and daily procedures, and that control is what courts and privacy doctrine use to determine who has the strongest reasonable expectation of privacy.

Independent contractor is incorrect because a contractor typically does not own the premises and works under terms set by the proprietor. The contractor’s access and authority are usually limited by contract and oversight, so their expectation of privacy in the store is weaker than the proprietor’s.

Guest on site is incorrect because visitors have a very limited expectation of privacy. Guests are subject to the proprietor’s rules and do not control store operations or business records, so they have little claim to privacy over the premises or daily operations.

Staff member is incorrect because employees have reduced privacy in employer owned spaces. Staff may have access to more areas than guests, but the proprietor retains authority to inspect work areas and records and to set policies, so employee privacy expectations are lower than the proprietor’s.
