I expect people to be polite. You can end the conversation without it being circular by just saying "see ya" or "talk to you later". It doesn't have to go on endlessly as you describe. Yes, I have expectations in behavior, and that behavior does not meet my standards or expectations, even as distant or polite acquaintances again. That's my standard. I don't understand your issue with it, especially since you're always espousing having higher standards from others.
