I found a website on who to tip on your wedding day and it says that for hair/make-up, if they come to you you don't need to tip, but if you go to the salon, you should tip. The reason being that if they come to you they are not paying salon fees. Is this accurate? Also, who else do you need to tip? My DJ and photog are both owners of the company. I know we'll need to tip the limo driver. TIA~
