Client doesn't have any idea what pages/links they want for their website. Same client told me to call the guy who recommended me to him for the project brief...wtf...I mean WTF!!!

Get used to it if you remain on web

Tell him that for that, you'll need to charge him a consultation fee.

One client asks me to do the project report and documentation also after coding! Worse thing, he asked me the objectives of the project

And once, he tells me all the steps in processing with all the formulas. And then I do exactly the same. Later he says that he wants the same thing differently! Wtf are those formulas anyway? I ask him why we should apply those transform at each point, he says, we should do it to get the end result right. But wtf, and how am I even supposed it do it differently!

DO. NOT. EVER. DO. THIS. SHIT. OVER. WHATSAPP. EVER.
