So Dev came and kicked/banged the door and she opened the door and Dev immediately lost all his anger and was staring at her and all he could say was Sonakshi...
She told him to keep it low (ofcourse as Soha is sleeping inside)... good until now.
Then she said she doesnt want to get into any problems with him and just asked him to leave from there ... perfect
but then she did not even give him a minute before saying "if you dont go i will call security and will ask them to throw you out of the hotel" -- this was not necessary.
This basically provoked Dev and he stayed put. He may have left if Sona gave some time. Then She called the front desk and repeated the same words "throw this man away etc"
She could have just said "please take him away instead of throw him away" .. anyways ... she was mad.. but sometimes wrong choice of words do create more issues.
