I get that secretive business that really got to me in the beginning. But I learned the codes, I learn which vague description equals which client. And if nothing else, I recognize the addresses of the places that I have been to, because that is apparently one of my superpowers, remembering addresses randomly for no apparent reason when I don't need to.
There really is no good reason why market Force can't post the name of the business on the job offers on their website that we have to sign into to see.
