Mind your Ps and Qs
It's not really a question but a comment. In your current listing you suggest that it could be to "mind one's pleases and thank you's" (k-you = Q) and I agree that this is far fetched. However, the origin as I was taught was that it was to "mind one's pleases and quiet's" i.e to keep your manners and speak when spoken to.
