See Dear Atif: If the solution which you have supplied is correct then there is possibility of one thing i.e. if I like tea he may order his peon/request his relatives etc. to serve me tea. But the question in the exam serves two purposes. 1) My desire to have tea 2) and if I desire to have tea then he himself will bring tea /serve me tea.


So your sentence talks of only one thing which is narrated in number one. I think this solution will be deficient.

We need to solve in a way in which both the purposes are covered.
