As you might know, H and I had a dry wedding. Between alcoholism issues in both our families and the expense, we decided not to have any alcohol. We even planned a lunchtime wedding reception so people wouldn't miss the alcohol so much. We still provided a variety of soft drinks including a custom Italian soda bar, so there was plenty to drink.
It has now been confirmed to me by several sources that FIL and BIL brought two trunks full of beer and flasks, and were serving his side of the family alcohol out of their trunks starting immediately after the ceremony.
I am beyond angry. I can't believe that they couldn't stay sober until fucking 3 in the afternoon. When the issue came up before the wedding, I specifically asked my in-laws to discourage people from sneaking in drinks. I am so damn mad and I have no idea how to handle this.
