I've experienced this. I think you understand it well enough. It is uncomfortable because it is a one-sided conversation and when you know that the person might think they are manipulating you into liking them, it is hard not to feel exploited.

I'm happy to say that some of the worst offenders in my life have improved their style over the years and respond to my answers with anecdotes of their own. They might still think they're getting me to like them but the conversation is interesting enough that I'm not annoyed by it.
