This happens every so often. They come in to make sure there isn't a girl working there with out a license. They may go into an occupied room to account for every girl in the building.
Very hefty fine for parlor if you have girls working not licensed. Everyone usually likes calling it a raid, but its far from it. No one ever gets hauled off for being in the establishment. Well maybe a girl will be removed from the building for not being a licensed massagist (sp). That's what they call it on a license.
I've been at Nevada's when they came in & walked around, checked things out. Stood chatted with us in the dressing room & looking through the book that contains all the licenses. Nothing scary & they are usually quit nice.
