If you're there as staff then you don't want to draw more attention to yourself then you have to. I wear my black watch in that sort of situation because the colors are so dark it doesn't attract attention. My ancient Caledonian is much dressier and colorful and is like waving a flag every time I move. I thnk you may have a better chance of wearing a kilt a second time if you don't make a spectacle of yourself the first time. Just a thought.
