Heathcliff diagnosed me with catgirl

Khan and Lore are the only two that immediately come to mind, but I'm sure there's plenty more cases of strangers aboard the Enterprise going "hey can I learn everything about how your ship operates" and the crew just being like "yeah sure here's a computer with unfettered access to all of our data, have fun" and like honestly What.

I think if I came aboard a naval vessel and went up to a crewman and said "hey can you give me all the records on how everything on this ship operates" they would probably not just let me have that.

Really after the first Holodeck malfunction they should have installed a cartoonishly huge plug you could just pull out to cut power to it entirely.
