While it’s true that you are going to come across difficult to please or plain nasty customers you should still pay attention to complaints. If the same issues come up several times you are probably doing something wrong.
That’s a good point. When I started I had several guys complaining about the photo on my page. Even though I always look good the picture was a bit outdated and I guess I’d changed since it was taken. I was surprised that it mattered – it wasn’t as if I’d posted a really old pic or anything.
Everything matters, the important things is to know how to make the difference between real complaints and teasing. Some clients only say some things because they can, not necessarily because you have made a mistake.
