Somehow the logic.
A rich lady shopping,
his footsteps stopped in front of a simple vegetable seller. At other times, the rich mother ate in a fancy restaurant with her family. After he finished eating he asked for a payment receipt. It says 415 thousand.
The mother issued a sheet of 100 thousand as many as 5 sheets, then gave it to the restaurant waiter who carried the receipt, then he advised. Just take the change. consider it as tips money.
Things like this often occur in society. Many people feel great when they can suppress weak people, but soften and reluctant to people who are already making big income.
Do not bid on sellers of vegetable sellers or foods sold by weak people if the price is still fairly reasonable, the intention is only to help through our care and the way of worship.
