I went to a wedding where they stated on their programs to not have your cellphone out at all throughout the wedding ceremony. I thought it was completely rude until now! I didn't understand it until my minister explain that we should put it on our programs. Since it will be a distraction and may get in the photographers way. So how do I politely tell guests to not have their cellphone out or post on any social networks. It sucks that I didn't understand it then on the importance of it.
