给你面子你就甩脸
[jĭ nĭ miàn zi nĭ jiù shuăi liăn]
It's a rather colloquial saying translating to: 'If I give you face/sparing embarrassment, and all you do is to put up a high and mighty attitude?' This phrase conveys resentment when someone is treated nicely, but then behaves disrespectfully or overly proudly towards that kindness.
