what is the store managers policy when a customer asks an employee to turn the music down? I asked and he did not respond. he just said that in the glass door room I should not be able to hear it but I can still hear it plenty. Loud vocal pop music..

Complaining to Corporate maybe the way to go here. I'm betting the music genre & sound level will change.

Loud vocal pop music is the last way that I want to start my morning after sleeping 14 hours and I am sure that all of the other customers feel the same way. If the music is going to be loud then the appropriate Coffee shop music is classical piano or ambience.
