[font="""]When a man removes his hat
A man should remove his hat upon entering a home, church, office, restaurant or movie theater. There are some exceptions to the “hats off indoors” rule: the hat does not need to be removed in some public buildings (the post office, airport, etc.), on public transportation and at athletic events. A man does not remove his hat in places where he does not seat himself, such as markets, grocery stores or shops. He also should keep his hat on in places through which he is passing, such as the halls and elevators of buildings or standing bars and coffee shops.
However, if and when he seats himself, he takes off his hat. Also, when a well dressed lady enters the elevator, he briefly removes his hat as a compliment to her. [/font]
