I attended a wedding yesterday where there was about 80-100 people (I suck at eyeballing). There were 12 chairs set up for a ceremony outside on a hill under a tree. Everyone was told "Chairs are for the elderly, like 49 and up" as they walked in. Which was a lie because there was more than 12 people in their 50s. I would say the most awkward part was, that only a quarter of the guests got the memo on this and that the B&G wanted people to bring picnic blankets and during the ceremony. So there's the EXTRA SPECIAL VIPS in chairs, 25 people on their own picnic blankets and another 50+ people standing or squatting during the ceremony. Lets just say a little distracting.
Besides that the venue was beautiful, and they got married.
