When a man is with a lady who recognizes an acquaintance, he must raise his hat, whether he knows the individual or not. He should, however, keep his eyes straight ahead, not looking at the person.
If he meets a man walking with a lady whom he does not know, he waits the man's recognition.
A man removes his hat in an elevator if women enter or are already inside.
This rule is often ignored in large public buildings.
If a woman bows to a man in any place where it is his privilege to wear his hat, he removes his hat and does not replace it while she is talking with him. This rule applies everywhere except on the street. "A gentleman of the old school" will stand bareheaded on the street if exchanging a word or two with a lady; in such case she may request him to replace his hat.
A man when driving or motoring cannot remove his hat. He bends forward slightly and touches his hat brim with his whip, held upright, in the first case, and raises his hand to the visor of his cap in the latter.
At Other Times.—When he is able to render some slight service to a woman whom he does not know, she will thank him with a slight inclination of the head and a smile, and he should raise his hat. When he relinquishes his seat in the street car, he should give the lady a chance to acknowledge his courtesy, and then raise his hat.
Men raise their hats and stand uncovered as a funeral cortege passes into the church or from a house, and at the grave.

They also stand uncovered when the United States flag is borne past, or the national hymn—the "Star Spangled Banner"—is played in public, at a military review, etc.
When a man passes a lady in the corridor of a hotel, or on the stairway, he should raise his hat.
