Since being in LA, I've been introduced to all sorts of dance studio models I had not seen before. Two Chinese studios I've been to have parties day and night 7 days per week. It's cheap to get in like $5. There are lots of people even say on a Tuesday in the afternoon. I am trying to understand the customs. Maybe you can explain... 1. There are DIs that get paid to dance with ladies mostly and I think they charge maybe $30/hour and up. It can be for up to 3 hours. 2. There is a couples area and you aren't supposed to disturb them. 3. I "think" there is tipping that goes on 4. There is line dancing in addition to traditional ballroom. What can you tell me about these studios and their policies/methods?
