Why do authors use enumeration?

Authors use enueration to overwhelm the readers with details. When trying to pursuade, many authors use it with benefits. For example, if an author is trying to pursuade someone to go to dinner with him, he might say "we wil have pasta, chicken, salad, cheese, watermelon, buffalo wings, ice cream, cake, pudding, jams, soda, juice, and a chcolate fountain." Who would deny that dinner? I wouldn't-- that is why authors use enumeration, the listing of appealing things makes it hard to resist.
