Even today, a man with good manner will politely open the door for a lady, help her put on her coat when it necessary and see her safely to the door of her home after a date. When a man take a woman out for dinner, it is considered impolite to help her with her chair when she gets up or sits down. On a crowding train or bus, it is proper for a man to offer a woman his seat, especial if she is old or carries a baby. Even when it comes to shake hands, ladies come first. It is impolite for a man to extend his hand for handshake upon first greeting. Unless a woman does not extend her hand to the man first, the man shouldn’t offer theirs.
