It depends a lot on what city you're working in and 2 weeks is still fairly new. When I started it took me about a month before I started really making money. Those first few weeks were so depressing- a couple of times I only made cab fare home! If I were you I'd try to get a feel for what the other girls are making.
If they've been there a year and are still making only $300 a night then perhaps you should look for a better club.Entertainers
