From Swami Satchidananda’s translation and commentary on the Bhagavad Gita:

Cherished by your spirit of sacrifice, the gods give you everything you want. (But remember) whoever receives gifts from the gods without offering anything back is a thief.

To take one hundred percent and give nothing in return is to be a thief.
To take one hundred percent and give only fifty percent is to be a debtor.
To take one hundred percent and give one hundred percent is to be a good business person.
To give one hundred percent and take only fifty percent is to be a righteous person.
To give one hundred percent and take nothing in return is to be a saint or a yogi.

We should always examine our transactions and discover in which category we put ourselves.

— Bhagavad Gita, Chapter Three, Verse Twelve
