Wow! I get that some people don't like wearing masks, but that guy's reaction seems pretty unhinged. Good on his wife for trying to deescalate the situation, but too late at that point. And in front of his kids, too - smh!
I'm glad security stood firm and didn't let the family into the park where another, less prepared, CM might have had even more problems. I mostly worry that people will wear masks properly to get into the park, and then try to dodge the rules inside, but good thing crazy outed itself before they even got in this time.
Mostly, I just don't know what they were thinking going to the park without proper masks for the whole family. By this point, it should be pretty well known that Disney and Universal are being proactive about mask wearing, and guests need to comply or postpone their visits until the rules change.
