I know that tipping is appropriate and common for hair/make up stylists and limo drivers. What about photographers? Also, since my reception hall is charging us 20% gratuity, should I tip even more? I'm not sure if the person I have worked with so far will be at the reception because I remember her saying that there will about 3 managers on site. Also what about those who help us at the church, such as a music director and alter boys?
