No relationship, business or personal, should doing tasks keeping score of what owed and what repayment they feel is just.

If you do favor, expecting one in return, or do good job expecting additional reward, you be sorely disappointed many times.

Do favor because you want to, with no score keeping. Do good work because you have sense of pride in yourself, with no expectation of gift at year end.

Have much happier life, with fewer dissappoints if you approach life this way.

No one is entitled to gift - ever. Not friend, not family, not business relationship. When get gift, view as unexpected bonus not entitlement.
