Yes, but isn't the client the employee's boss? We do a lot that is to ensure compliance with government regulations. It is much cheaper for the employer to identify the problem using mystery shoppers than wait for the Feds to send someone to and pay fines and penalties.
Granted, I think that lots of shops should transition to video, but compliance shops are a real natural. No relying on anyone's memory, it is all there. Recently I had some new ones and while the MSC ordered a traditional shop, I took advantage of Missouri being a one-party state and used my video cam. I knew that under the circumstances there was no room for error on my part.
Equal rights for others does not mean fewer rights for you. It's not pie.
