'I said shut that kid up!': Boomer yells at 5-year-old in a children's museum during an educational movie, snores through the entire runtime

There are a lot of people who hate kids for no good reason. I understand if you don't want a family of your own or you get irritated by babies crying on an airplane: this isn't about you. I'm talking about adults who, for some reason, expect children to adhere to adult maturity levels, even if the time and place don't call for it in the slightest. This is one of those situations. Parents brought their daughter to a children's museum and were shocked to find a baby boomer man shushing the children. Not only was he shushing them, but he was alone in the museum movie theater, snoring through the entire educational film. If you dislike the sounds of happy children, why would you come? Also, why are you there if you're not a father or a grandfather? Why was he allowed in the door? So many questions need to be answered here.
