A fool demands much, but he's a greater that gives it.

The saying rebukes not only unreasonable demands but also indiscriminate compliance. Someone may be foolish to ask for excessive help, money, or concessions; yet the person who grants such demands without judgment is portrayed as an even greater fool, not as socially greater.

It advises restraint and discernment in giving. Generosity is not automatically wise when it rewards greed, enables poor conduct, or ignores one’s own limits. The proverb shifts attention from the requester’s folly to the responsibility of the person who chooses to yield.

Use it when cautioning against giving in to an excessive or unreasonable request, especially where compliance may encourage further demands. Its blunt, judgmental language calls people fools, so it suits criticism, advice, or wry discussion rather than sensitive situations.
