That’s just to deter people from stealing. In public spaces and semi-public spaces consent does not need to be given. A store is considered a semi-public space.

That’s just to deter people from stealing. In public spaces and semi-public spaces consent does not need to be given. A store is considered a semi-public space. There is no expectation of privacy in a store. Anyone can take pictures of you and record you if they want and you legally cannot do anything about it. You do not have to leave the store if you do not give consent unless you don’t want to be recorded. You’re still going to be recorded in the parking lot.
