Amtrak lets the chips fall where they may, but not on children without an adult present

I don't understand the nanny state.  Amtrak's Coast Starlight route has a lounge car, called the Pacific Parlour Car, for passengers who book sleeper service.  It hosts a wine tasting in the afternoon, and according to the information on the train, children aren't permitted in the lounge car during the wine tasting.  On a recent trip, Amtrak's personnel (uniformly friendly) welcomed the Laquedemitasse to the wine tasting, and plied him with extra cheese and non-alcoholic apple cider, despite the rules.  On the other hand, he wasn't allowed to buy potato chips at the snack bar without parental supervision.
