Dint Rubina, Abhinav and Nikki know that taking her coffee means rules breaking? They Firstly manipulated her to keep it with them and had it silently and were so shallow when she shared with others like seriously acc to them they are the only ones entitled for any privilege. Rightly Rakhi mentioned how they are the ones who properly had coffee and Ali, Devo bechare just had one sip and still miss Ruby had the audacity to blame them. Not just that the way shameless Nikki was laughing when Rakhi's coffee was gone was so disgusting. Truth is Rubinav and Nikki dint care a damn abt Rakhi and her coffee and it dint matter to them if its gone. They just played with her and fooled her. I would give Abhinav benefit of doubt here cos atleast he was decent enough to ask before taking.
