I have a venue that includes food, alcohol, servers and bartenders and my fees include gratuity. Who are the vendors that I provide tips to? The ones I can think of most obviously are, hair dresser/make up artist but I also have a photographer (who I will be giving a meal), officiant (who I intend to offer a meal), florist, cake baker, linen delivery. I also have a coordinator who is included with the venue. I'm so bad at this and I need to be super organized! And how much is customary?
