Venue/Catering - include gratuity in final bill, so I don't need to tip anything additional correct?
DOC - owns her own business, so no tip?
Bakery - same as DOC?
DJ - works for a company, so he gets a tip?
Ceremony Musician - two people splitting 50/50, do they get a tip?
Lighting - same as DOC?
Videographer - same as DOC?
Photographer - this is the one I most confused about. I hired a photographer that ended up moving and asked another photographer friend to fill in for her. I should probably tip the replacement photographer (as I don't know if my hired photographer is paying her or if it's just a friend doing a favor for another friend). How much would you tip percentage wise?
