«جَعَانْشِي أَفِت لَكْ؟»

The question sounds generous but quietly undoes itself; it works rhetorically rather than as a sincere inquiry about hunger. Someone who truly meant to feed a guest would simply set the food down without asking first, since a hungry person may be too embarrassed to say yes or to ask for a meal outright.

The saying therefore targets anyone who offers a favor or help while privately intending never to provide it. Its force lies in the gap between the courteous offer and the speaker's actual intent; it is not praise for hospitality.

Use it about someone who proposes doing something for another person but clearly has no intention of following through. It exposes the polite offer as hollow, since real goodwill would show itself in action rather than in a question the other person may be too shy to answer.
