I've had alot of encounters like this. My pet peeve is backpacking on the AT and resting at a shelter to get water etc (before moving on) and watching so-called "expert" thruhikers "Hold Court" whereby an individual thruhiker will make his presence available for anyone wanting to ask questions---but him--himself (or herself) NEVER asking one question from anyone in his "audience". It's comical and possibly infuriating. I call it Holding Court---as in "I will now deign to take your questions."
One time I went along with the madness and asked Our Lordship a simple question---after he went on and on about his expertise---"Have you ever backpacked and camped in the snow?"
He said, "No, never in the snow". Oh okay---so much for the Guru of the Appalachian Trail.
And to the OP---if such behavior bothers you---find areas to go backpacking where your chances of seeing anyone is practically nil. I can give you a long list.
