In a city with flags, on flagpoles one longer than the other, acting like territorial markings of Maratha, Meem, Bhim, Rashtravadi, etc., each one with leaders claiming to be more patriotic than the other, here's one society that decides to use the Indian national flag.
You will rarely see a flag outside societies in the upper middle class range. The reason could be that most of them are not easy to extract votes from.
