A: Why is the soup so salty?

B: I guess the cook put the amount of salt called for into the soup and then some.

Note: This idiom is an age-old idiom that has become a cliche. It means “and then some more,” that is, more than has already been stated. Sometimes people say it out of habit as a form of emphasis and you’re not supposed to take it too seriously. For example, a hotel manager may boast that their rooms have everything you want and then some. No one is going to take it literally.
