Suppose a customer enters a store. The business, through an employee, treats the customer unlawfully. Perhaps this is by verbally or physically abusing them, discriminating against them, or denying their consumer rights or rights as a member of the public. The customer begins to film the employee using their phone, and the employee strongly objects to the recording. Meanwhile, in case it is relevant, the business is constantly recording everyone within the premises with its CCTV.
The customer is an individual who will only be using their recording for private household purposes. But they are informed by the indignant employee(s) that they have no right to record anyone without their permission.
Does the employee, in a purportedly individual capacity, have any grounds to object to the customer recording them “without their consent“?
