I know there's a Knot tipping guide, but curious what real people think/do. Some questions: what percentage and who do you tip? If your caterering bill includes an "administrative fee" percentage, how does that, if it does, affect tipping the catering staff? Do you tip your photographer, if he owns the business? The hair or makeup folks, if they own their business? The Maitre D? The florist? The cake baker who delivers the cake? The secular officiant? And how much? Thoughts? Suggestions?
