«عَامِلْ عِنَبْ وِالْبَاقِي فُرَاطَهْ»

The saying ridicules a conceited person who acts as if he were the choice cluster still on the vine, while everyone else is فراطة: grapes fallen loose from their bunches and sold for next to nothing. Here عامل means posing as, not a worker, and فراطة means loose grapes, not small change.

In practice it targets arrogance and self-importance, especially an inflated sense of worth that depends on belittling others. Speakers use it to deflate someone's pretensions by pointing out how absurdly the person has ranked himself above the people around him. It judges that self-ranking, not anyone's real quality, and is never praise.

Use it as a mocking remark about someone who carries themselves as superior and treats peers as inferior. It fits gossip or teasing among people who know the target, and is pointed rather than polite. Avoid saying it directly to elders or in formal settings.
