That one client wanted to hire me and a friend for a small 2 month C# school project basically reformatting and redistributing incoming forms. In the last meeting before we were supposed to start the project he told us that it was supposed to be a sharepoint thingy.
We declined as we never worked with sharepoint, not to mention the Clients indecisiveness​ regarding what he wanted.
The ridiculous part was really that a lot had already been set in stone and we had to find another contract in 3 days time.
