Inspired by another thread.
I assume people who work where they can't divulge who they work for have cover stories. But do the cover stories have "proper" employers with Pay slips, NI numbers etc - so if you had to apply for a mortgage, credit, renting etc, the person enquiring could see a pay slip and say, ok, I'll give you credit.
Are there "switchboards" so someone answering the phone call knows how to answer to say the company name?
Even James Bond needs a place to live and a credit history.
