To give real service you must add something which cannot be bought or measured with money, and that is sincerity and integrity.

The line contrasts the transactional side of “service” (what can be priced, purchased, or quantified) with the moral and interpersonal qualities that make service genuinely valuable. It argues that sincerity and integrity are not optional “extras” but the decisive elements that transform a paid task into real service—because trust, honesty, and authentic concern cannot be reduced to a fee schedule. Read broadly, it is a critique of purely market-based notions of value: some of the most important contributions in work and public life are intangible and ethical. The quote is often used in business and leadership contexts to emphasize character as a core professional competency.
