Well said, Bart.
There was woman working in my shop who only wanted to render images brought to her by customers. She didn't want to draw ANYTHING. Her portfolio did not reflect that at all to customers as they saw these really nice, rendered portraits or statues or whatever. Since we refer people to portfolios so they can choose who tattoos them, MANY people wanted to get tattooed by her. When asked who they wanted to do the job, many people picked her based on her portfolio. The next question is "What do you want to get?" "A script name," they often answered- not knowing that she could take a perfectly good portrait and fuck it up with her version of a script name because she didn't care enough to learn lettering well enough to make it match her renderings. It was not uncommon for her to Google "Fancy Script" when she could get away with it.
In this case it was a matter of a tattooer who didn't care and some customers who in a lot cases just did not know what they wanted. This of course, did not keep them from giving unfavorable reviews of my shop and their experiences online. She no longer works with us and it changed the environment in our shop for the better.
