How do you say "Tip people $20 and they will sometimes give you what you want." in 2000 words or more?
I'm taking a writing class right now, and they really stress that real-world examples explain your argument better and make the writing more interesting, and I think that's actually true.
That said, giving too many examples makes it too long to be worth people's time and/or bores them with too many examples that are too similar.
