Get the axe to grind mug.
To have an ulterior motive, especially hidden behind a friendly demeanor. From a story attributed to Ben Franklin and later Charles Miner, in which a friendly stranger asks a youth for the use of a grindstone to sharpen his axe, but tricks the youth into doing all of the work.
"When I see a merchant over-polite to his customers ... thinks I, that man has an axe to grind."
