Shivangi doesn't know what is ''Chai patti''??I mean really??Well,it doesn't prove that Shivangi is ''dumb'',but it certainly proves that the SCRIPT-WRITTER of NB are either dumb or they think the viewers are dumb..You dont need to go to the kitchen or read general knowledge books to know what is ''chai patti''..Just switch on the TV n see Madhuri Dixit,Saif Ali Khan and various other actors telling you about what ''chai patti'' is..
