What does "handing salt" mean in English idioms?

^_^

A couple are having a romantic breakfast. The woman looked at her lover for a while and said, "Dear, I love you." . That's what women do. Romance has no time, and sensibility is absolutely supreme.

A man may butter his toast, or he may cut a small piece of bacon in a hurry, thinking about a meeting in the morning or something. Well, it would be better to add some salt. "Give me the salt." He said. Men are never animals that can't maintain their passion.

After marriage, women need some sweet words more, while men pay more attention to practical things and are no longer willing to talk about them, which is a waste of time.
