Just a few of the issues: music selection, sound/speakers, unnecessary and unprofessional announcements.
When discussing the microphones, I questioned if we all needed one, and described that my voice carries much more than the groom. I fou...nd out later, per the guests and mother of the bride, that only the preacher and myself could be heard. For whatever reason, the groom had to share a channel with the reader. During this process, he could not get the mic to turn back on after her reading. The ceremony had to continue and he was not heard, which was my worst fear.
We started releasing tables for dinner around 5:45 when dinner wasn't to start until 6:15pm. The bridal party was not released first.
The kitchen had all sorts of equipment malfunctions that day, however that did not need to be addressed to the wedding guests.
Money was an issue the morning of the wedding. I was confident that we had already settled the bill, but come to find out, there was yet another charge.
Also, we used the planning forms for the music and he continued to play the "dinner playlist" even though the Groom insisted something more lively. We didn't hear our songs until the last hour of the wedding.
