Rudest moment at your wedding/or weddings you've attended

OMGG, talk about drama! All the anticipation and the hard work and hopes that go toward making the wedding day come together…and some people just can’t allow the bride/groom and their families to look back on it with fond memories. They have to destroy the occasion for the people it matters the most for…with their own pettiness. And the offender might move on from it…but things like this can linger for the bride/groom. I think the first and the last stories you shared are the worst.
