About 10 years ago I did an interior for one of the largest firms in Lebanon. I was given a huge plan of a hall with 4 walls. nothing else. I was told to design it. First thing i did was setup a camera inside these walls then I went to the client with my notebook to decide where he wants the camera. I later was told by employees that he told them he almost fainted when he saw the 4 walls with no details. They want fully detailed renderings in 1 day, so that they can change the design and have you redo the work the next day and so on. In the end we focused on a small corner of the huge hall. So I was right in not modelling the whole hall to discard most of my work later.
Another client cancelled the project and asked for a refund of the retainer after the first previews despite me warning her that the fist preview is just basic walls just to set the cameras. She claimed her husband changed his mind. But I know she did it because she didn't understand it is an iterative process.
Other clients told me that natural disasters that delayed a project should never happen again as if I can control fire that took out a power plant where I live, others told me that they hesitate to hire me since I am a lone freelancer in case I die in the middle of the project. I heard so many depressing things I can write a top ten.
An uneducated client is a life sucking ghoul.
15 years doing this 12 hrs a day and it never gets easier to deal with clients just harder. Can't wait for retirement.
As an employee since last years after 10 years of self employment, believe me being employed protects you from having to deal with crazies, especially if where you work management is caring for the employee is I have here.
