No one has evern mistaken me for being their waiter, and I do visit as many of the folks sitting a their tables as possible while performing in restaurants. As DNJ always says "Ya' gotta's Schmooze a little!"
One of the things I've always prided myself about is dressing properly for the occasion. During the cooler months I always wear highly polished dress shoes, black slacks or tux trousers, satin shirt with matching tie and a vest. Some jobs, particularly high end parties, and or course NYE, it's a tux, vest, the works. Summertime jobs, especially in relaxed atmosphere locations, black slacks, highly polished shoes, Hawaiian shirt. If you look and act like a professional, you'll be treated as a professional, and hopefully paid well for your performances.
Cheers,
Gary
