A few weeks ago, I was doing a wedding at an apple orchard. They have an indoor facility, but for some reason we were in the pavilion. And the indoor facility wasn't being used. I'm booked until midnight. The owner of the facility comes to me at 10 and says our neighbors called and they clearly hear every word of your music. It's way too loud. You are going to need to turn it way down. The neighbors get mad if they can hear the music after 10.
(It wasn't that loud. People sometimes mistake clarity for volume)
The dance floor was packed.
So I told him, well I'm booked till midnight, and that's something you should have discussed with the bride and groom when they booked the pavilion till midnight. You tell them and and they can tell me to turn it down. But I'll adjust it slightly for you.
He did go to the bride and groom. After a long discussion, the groom came over and said, "ok turn it down just a bit. That guy never said anything when we booked about having to be quiet after 10.
