My favorite result of that law was when I stopped to get gas in Washington state near the border with Oregon. I made eye contact with two 20-somethings that were arguing back and forth about something. After I'm done one of them worked up enough courage to approach me and ask for help. Being from Oregon, this was their first attempt to fill up a car on their own, and they couldn't figure out how to make the pump work (they didn't push the handle with enough force to engage the vapor recovery).
