It's funny, but years ago, when I sold services on Fiverr, I'd charge much more than I really wanted to charge, just to ward off the possibility of attracting a whole bunch of clients, that only wanted to be difficult and micromanage me. I figured the fee would either be a deterrent, or at the very least, I'd be adequately compensated for putting up with B.S. I got way less orders, but the strategy appeared to work :-)
