For your entertainment..
About a year ago FI and I were invited to his friend's wedding. We RSVP'd by the date, went to the ceremony which was outside in November in NYC with no heat. It was freezing. Needless to say we were already peeved as we were walking into the reception. There was a seating chart and SURPRISE, we weren't on there anywhere. Rather than try to hunt someone down and cause a scene or whatever we left. I ended up getting an upper respiratory infection the next week from sitting outside for an hour long frigid ceremony. It totally ruined our moods, until we went a bought some steaks and a few bottles of wine on the way home.
