It is a food safety violation to wear any jewelry in Target Cafe, Starbucks, Deli, Bakery, etc. You can't wear earrings, nose rings, bracelets, watches, anything. The only things permitted are a plain wedding band and medical alert bracelets. It's not just a Pizza Hut thing. As for nose rings, there are the clear plugs that will allow you to keep your hole filled, but won't be visible to anyone else.
