I've also read many people saying it was out of line. I don't think so. It's called get your dues!
But yes, if you intend on doing something like this, don't rule it out to begin with because that makes you look foolish. And Sonali did go up to the camera and say that she won't do this because it's insulting. By looking in to the camera and making this statement, she made herself look silly. It's as simple as that.
Gotta say though - Gautam's reaction was classic 😆 and Praneet's cheeky smile...I loved it!
