Depends on how bad and who they are. Unless I've been asked in an official capacity at Piper's school, though, no. And even then I've only spoken to one person who didn't ask. He was dropping off his daughter's seat for a field trip and I saw the red lockoffs and the old base and knew his Roundabout was expired. I told him so, told him to call Britax (I find people take the news better that they're screwing up if it's not just me saying it, if they call the 800 number someone else will tell them too) and his daughter borrowed one of my seats for the trip. But in North Carolina that seat is illegal to use (proper use state). But otherwise, no. I tell Piper, though. I told one child, actually. One of the kids I was driving for Piper's field trip came without a booster. He used one of mine. He's seven years old and no way would he pass the five step test. So I told him, he told his mom, and the headmaster called me while his mom was at the school and I told her about NC state law and the five step test. I don't know what happened. The school is very on board about me helping out, so if I ran my mouth off and told just about every car about their errors they'd back me, but it's too exhausting.
