I legit had this happen once, but with my wife and I. Thought we were the only two in the theater, and just as the trailers end a guy pops in and walks all the way up to the back row and sits down next to my wife. We were in motion seats that you pay specifically for, if the other motions seats aren’t reserved they don’t function. So we couldn’t ask him to move. Worst part was about halfway through the movie my soda caught up with me. I sat for over an hour having to piss badly because I couldn’t leave my wife alone with some strange ass dude

I don’t think awkward “social experiment” weirdos are a protected group
