I'm the MOH in my best friend's wedding in 6 weeks. She's having a make up artist come to the hotel in the morning and while it's optional for the bridesmaids, we all talked it over and are getting our make up done. It's costing $75 a person, which I feel is a little high, but don't want to make a big deal about it for the bride's sake. However, who is responsible for tipping??? Do we each have to tip the artist individually or is the bride responsible since she hired the artist?
