DH is a groomsman. The couple married a year ago, and isn't hiding that fact from anyone, but...still.
I can come back with an update if anyone's interested, but so far it's been a shitstorm. Bachelor party in Vegas, planned by the groom, without asking anyone for a budget. The tux rental for DH was $300. At the rehearsal dinner last night, one of the bridesmaids freaked out over something, I don't know what, and removed herself from the wedding. Also at the RD, I asked what drinks were covered and was told it was open bar. At the end, everyone who ordered hard liquor received a bill.
The event today features a horse-drawn carriage to start an outdoor wedding. It's 106 outside right now. I can't wait. I'm sucking it up because its DH's best friend.
