Tattoo artists of reddit, have you ever seen a customer unhappy with a job at the end? Any customers out there who have been unhappy at the end? What do you do?

I got to thinking about tattoo shows like Miami Ink etc. and there a customers so specific about their tattoos, but what if they get the initial designs done and are impartial to it, but get it anyway, and then at the end of the tattoo they are unhappy? Does this happen a lot? Do the tattoo artists get crapped on?

It seems kinda funny if it would happen :P But at the same time it would suck.
