Rashami is asking for a partner. And after Arhaan was evicted the complete dinner food making is on her because there is no captain to allot the duties. So for a person to cook for more than 10 members alone is not easy. She has to prepare rice, curry for all of them. Then for Rotis we are not sure how many rotis each person eats? Some may eat 3 or 4. So by that way she has to stand and make rotis in front of stove. It is difficult.
And have you listened he said something like conveniently bimaar pad jaathi hai. What is he trying to say?
And also when he was saying Vishal ka liya tha Vishal ka liya tha Vishal ka liya tha, his body language was very annoying. And also the way he is imitating Rashami in front of Vishal.
And when people generally cook, if there is a partner the work load reduces and they can talk while cooking which makes them feel nice to do the work.
