Music is nice, but not at this volume

Every Thursday night here at the museum, we feature free live music in the lobby. Tonight it is "Hot Latin Jazz for a Summer Evening." I have never worked the evening shift on a Thursday, so I am totally not prepared for this. The music is great, and people are into it, but holey rusted metal batman, it is so LOUD! My customers are getting angry with me because we can't hear each other talking. Plus, it is so much harder to sell memberships over there.
