I am reading a business letter, and I have come across something I do not understand at the closing of the letter. What does rq/s mean in the following context:
(Body of letter)
(name of sender)
which indicated that the letter had been dictated by Albert B. Connors (ABC) to his secretary, David Eaton (de) who then typed the letter.
Is it possible that 'rq' are someone's initials?
