Success Mantra: Everybody should complete their duty

That was a long time ago. The program was going on in a school in Pune (Maharashtra). The volunteer was kept for this program. His job was to welcome and greet everyone who came in the program. Chief guest Govind Ranade came in the program.
As soon as Govind Ranade passed in front of the volunteer for admission in the program, he was asked for an invitation letter. Ranade did not have an invitation card, then he refused. Said that I do not have a letter.
On this, the volunteer replied politely, then forgive me, I can not allow you to get in. After Ranade, there are many donors standing right there at the main gate. Seeing them, the organizers of the program ran and ran inside. Seeing this, the volunteer standing at the gate said that I do not like to discriminate. And my duty was to do my work properly.
