The beggar is never out of his way.

A beggar can seek help wherever he goes, so taking one road rather than another need not put him off course.

More broadly, someone whose purpose can be served in many places has little reason to regard a change of route as a mistake.

Use the proverb when a supposed detour makes little difference to someone who has no fixed destination or can pursue the same aim wherever they go. It can gently challenge the idea that there is only one useful path.
