I understand it's upsetting to see your culture not represented properly.
But this is a fictional show, and like a poster said the jeers jaggery thing is more important than pheras, a person from another part of india wouldn't understand that.

Don't take any offence, makers often take creative liberties, besides if they showed all rituals then the wedding would carry on for a couple of episodes.
I understand your frustration, I also belong to a very misrepresented community. They only show my community as jazzy, eating papad and saying wadi saeen (which we don't use). But I've learnt to sit back and enjoy
