they are doing to him what they did with Asif. Salman is being rude to Asif and so he is doing it the same to this guy also.
But I think if you have to compare anything This guys body is way better then Salmans. They both are the same hight, they sound so much alike.I think the part about doing SRK was very rude of Salman. Why did he not say do Aamir s voice then Salman.When you have to compare Salman acting to SRK there is no competition at all.
