See, that's the thing... once I'm done listening - that is, I've heard all I need to - I simply make my excuses and leave. I'm a busy man, after all.

[A busy, busy man who doesn't have the time to be standing around chatting to some elderly woman about a cat she had that died three seasons ago or listening to someone talk about how they're having trouble moving their stock out of a warehouse.

He has absolutely no problems with wrapping up a conversation when he's had enough of it and bouncing, and people usually forgive him for these eccentricities because he gets the job done. And if they don't... well, they don't really have an option in the matter.]

But it sounds like you have some personal experience with being on the wrong end of a conversation you couldn't get out of.
