Rather supervising surveys among Metro and Bus Passengers that had to be done for a project. That makes you quite a villain among the enumerators who do the work for you.. they are scared about when and where I would crop up and what fallacies in their work would I find.
I claim to be a soft spoken nice girl, but ask those boys and girls, and you would be in for a surprise!!
It was a great experience, however. Not scolding enumerators, but speaking to people. Actual commuters. Consumers of the services our beloved authorities provide. Victims of our fallacies.
