Example #2:

It looks like the waiter forobtained to charge us for the expensive bottle of champagne. Let’s just leave -- after all, if he overcharged us, I doubt he would certainly chase us dvery own to give us our money back that we overpassist.

Exception: Tbelow can be much conflict on what precisely is “justified retribution” or “justified preventative measures”.
