That’s hawt!
IME It’s more to do with it being too far down.
He’s wrong about the proper order in the five-urinals scenario. The first guy in should take the middle one, because the next guy will easily figure out he has to take either #1 or #5, which leaves the one on the other end for the third guy. If instead the first guy should choose #1, say, then there is a real possibility that the next guy will thoughtlessly take #4, leaving a dilemma for the third guy who walks in.
It’s possible that this objection has already been made among the 469 comments there, but I did not feel like wading through them.
True story: this happened to me. Then the guy spead his jacket over his lap and started masturbating.
It did indeed freak me out.
Relatedly, there is the Greyhound paradox, where it is actually considerate to sit next to a stranger when there are completely open seats available. You should explain to your neighbor that this is mutually protective in ensuring that neither of you will be seated next to a weirdo for the whole trip. At least on the routes that I have had to ride, it is always vain to hope that the seat next to you will remain empty.
