Is it normal to a person at bar to think you besties

So I went to this bar and got my usual. Which is usually whiskey&Coke or Whiskeysour. I only ever get whiskey drinks. I always sit alone in a corner and get 2-4 shots of it. I sometimes talk to the bartender but not often other patrons. So recently I been in school so haven't gone as much. However yesterday had a day off becuase proffesor canceled class since he had family emergency. The bar was very busy so it was hard getting bartenders attention that night. So this awkward fellow tried getting the bartenders attention for the few who where in the corner trying to get a drink. Than invited me hang at thier table and walked outside. I got my drink and ignored the invitation and found a table in the corner as I generally do. So they came over and asked "Is something wrong?". So I humored the idiot and sat at his freind table. After which it seems he tried to what I would describe as trying to "Therapy me". Saying things like "Do you feel alienated" and "You have a freind in me" bs. To which I replied I "Came to the bar alone, on my day off from class, and decided to drink alone which was interpreted by a fellow bar goer who wanted to chat about thier feelings. When I did not really care". I'm unsure of what this fellows purpose was. Who makes freinds at a bar? Also who talks to a new person for an hour and automatically like "Oh we besties now!" And trys to therapy at a person clearly content with being left alone.
