«اِللِّي مَا يِفْضَلْ مِنُّهْ جَعَانْ»

Rather than asking whether someone has eaten enough, the proverb lets the bottom of the dish give the answer: when not a single morsel remains, appetite is presumed to be still at work.

The same reading carries over to any case where someone draws a supply down to nothing. The emptiness left behind serves as a visible sign that the person's need or desire for that thing has not yet been met.

Someone might say it on seeing a dish wiped completely clean, or extend it to anyone who uses up every bit of something on offer, hinting that this person would gladly take more.
