Confession: some of the talks I've had with people at the dinner table in the diner makes me glad I have a roomette and can get away from people. (Extreme introvert here). I remember one really rude passenger who basically snarked about everything....asked me what state I lived in, I told him, he said "Oh God, why would anyone live there" and talked about all the hicks and rednecks and stuff. Attacked Christianity, too, and claimed his own "path" of Buddhism was far better. (Every other Buddhist I have known didn't give a flip what faith path others followed. ) I know it tells me more about him than it does about me but it was a really...unpleasant dinner, and had the diner not been full (and me hating making anything like a "scene"), I'd have asked to move to a different table.
Maybe that's how he got his jollies, upsetting young-ish female passengers, I don't know, but it was really unpleasant and I even contemplated eating breakfast in my room to avoid the risk of encountering him again,.
I have met a lot of nice and interesting people, people into organic gardening, one who was a retired campus cop from my undergrad university, someone who did industrial archaeology (studying old factories and the like).....but that rude dude is the one who stood out.
