How can you fire someone who you say without any hesitation that you wouldn't hire in the first place? Tattoos can be covered up and piercings can be removed. You think they will mistreat your customers so why even bother hiring them. Or even if they give a good interview (by removing the piercings and covering the tattoos), you still wouldn't hire them from fear of offending your customers. The fact that you equate disrespectful behavior with appearance is exactly what prejudice is.

The statement wasn't about appearances but about names. Names on resumes. Since when does a kid have control over his or her name? Should kids be forced to change their names because their parents choose a name that people call "ghetto"? How is that not prejudice?
