vulgar. You ask why? There is no reason. People with the widest social experience and the best breeding just don't do it that way, and that is all.
It is in quite good form to omit titles in the formal note and call every man plain 'Mister' though the one who does this will sometimes give offense to judges and doctors of medicine, and to military officials, who commonly adhere very closely to the titles to which they can legitimately lay claim. A friend of mine, a high college official, was introduced by a physician as "Mr. Jones" though he was entitled to be called "Dean," but when he in turn introduced the physician as "Mr. Brown," he was corrected by the medicine man and reminded that he was "Doctor Brown." It is well, therefore, to keep these points in mind, for though it is never discreditable or discourteous to call any ordinary man "Mister," yet some men will not like it; and more women will object if their husband's titles are not recognized. If you ignore the convention, you must not be annoyed if some people think you do not belong in the first class.
It is a general custom in formal notes
