SI scars hiding question... job interviews?!? (please opinions helpful)?

I don't know how all places of employment are but I have worked at a banquet hall, a sandwich shop, as a waitress in a restaurant, in a theater, and on a college campus and no one ever had a problem with me wearing long sleeves. A lot of my uniforms had short sleeved shirts but it was perfectly acceptable for me to wear a long-sleeved shirt underneath. When you go to the interview ask them about their dress code, they'll tell you what you can and can't wear.
