I've worked at studios, so having dealt with the overzealous fans before, I would never imply that I knew something I wasn't allowed to discuss. It just invited further conversation, and to be honest, harassment from a guest who then thinks I'm withholding something from them. I would probably say, "I'm sorry, I wouldn't know."
When I was younger, being a CM was common job for college friends or a second job for co-workers. Many, many times I've heard stories from friends where over enthusiastic guests would challenge the CM's on what they thought should be protocol. Like telling a ride operator that there was trash in the queue and then getting bent out of shape when the CM didn't pick it up. There shouldn't be trash, so they reported it. Then they'd have some level of indignant response ranging from mild to major, not really stopping to think that the CM can't leave their assigned position to pick up some trash. There are custodial CMs for that. What I've read of this thread strikes me the same way. A CM, alone, near a ride, possible working on another ride (in an assigned position) or maybe working alone at a cart was asked what time something closes. The answer didn't meet with what the guest read on the internet as "Disney policy." So what? A CM scanning in hundreds of people per hour (something people on this board complain about takes too long daily" didn't have access to personal information about when a guest's AP expires (something the guest can easily look up online or in the app) and responded with an honest answer instead of stopping the line to formulate a personal response. What was the expectation here?
