This is only somewhat true. At the spa for instance, you very much have an expectation of privacy. Practically speaking it is sort of contextual? Even at say a restaurant, I would be both surprised and disconcerted to discovered the business had recorded the entire conversation that occurred at my table, even though I would be unsurprised by a bit of eavesdropping.
