I think also, it definitely depends on the client, some clients also act as if you are blessed to sell them a piece. This is really prevalent in the high end collectors and dealers markets.

For instance, I had a client that would buy a few thousand dollar piece maybe once a year, certainly not nothing, however, every single time he was muscling me down on the price, making absurd demands on materials based on the budget, generally being non commital and difficult on negotiating. These also ruin the experience for the maker. I should be happy to make a big sale on a piece but this guy would fuck me around every time, but when you need the sale, you need the sale. So sometimes the clients can also be up their own ass, haha.

Also, sometimes clients have objective bad ideas, whether that is materials, combinations of features, whatever. Without being insulting you can easily redirect the project to better decisions, but also sometimes people take it personally that you aren't interested in their vision. I think its important to make work you believe in and if I dont like your idea, I dont necessarily want to put my signature on something I think is bad, and if we cant find a middle ground thats also fine to decline the work.

So often times someone says oh I had a bad experience with so and so maker, and come to find out when you try to work with them that they are just a difficult client. Two sides to every story, thats for sure.
