"Yes thats fine" is usually used after a statement has been made by another person that is demeaning, demanding, pointless or even needlessly correct. "Yes thats fine" derived from Tom Goes To Mayor, although slightly bastardized (as the Mayor said only "Yes, fine.") but still serves the same purpose: to shut down the person speaking.

For instance: if someone is discussing something with you they take very seriously, and you respond with "yes, thats fine" it often will show the speaker that you don't really give a shit. Other times it confuses them and gives you several seconds of recourse before they resume.
