This happened like 6-7 years ago when I used to do some logo and Web theme designs as a side job. There was this motel owner client who wanted me to make a website for him . he didn't give me much to go on except some themes he liked and some pictures of the motel. I finished the website on time but of course he didn't like it, he told me that he wanted it to be bluer(?). So I played with the colors a bit and showed it to him a couple days later, but now he didn't like the font that I used he wanted a font that stand out, like those Gotik ones; I politely told him it would not look professional when he refused I told him it would look like a teenage Lamer at Tumblr. After that he settled down for a less idiotic font. I finished the final cuts the next day and went to the motel to setup the website and show him how to use it. After a good hour of teaching him in the ways of the Internet I told him I needed my payment now. But the guy only wanted to pay half of what we agreed upon because I delivered it late and also didn't do his requests. I reminded him, that this is my job I worked hard for this. That he owed me what he promised. His counter argument was That all I do is press some buttons on a keyboard and that I don't know what working hard really means. That was the last drop. You see I usually have somewhat good pr skills but I can only tolerate limited amount of bulls*** at a time. So I deleted the www folder from filezilla and told him to go F*** himself and left. Never been a freelancer ever since
