1)Hash-m doesn't take shochad.
2)You show them favor.
3)How can I not; they bentch on a k'zayis/k'betza
Question: isn't then the bentching shochad. We "bribe" Hash-m with the bentching. He let's Himself be influenced to give us special treatment in deference to our bentching.

If Yisrael "bentched" in order to gain favors from Hash-m, that would be Shochad. But if they do so because they love Hash-m and want to praise Him, that is not Shochad, and Hash-m is perfectly entitled to reciprocate and demonstrate His love for them. "Ani l'Dodi v'Dodi li!"
