Why do you think Professor Gaitonde decided never to preside over meetings again?

Explanation

In the alternate reality of India, Professor Gaitonde attempted to take the vacant seat in front of an audience that he was so acclimated with, just to be met with antagonism from the group, who tossed eggs and tomatoes at him and ran him off stage. The effect of this episode on him was so awful, so when he thinks about his thousandth addressing as a chairperson when he gets back to his actual reality, he won't preside over any more meetings again.
