why is an extras girl an extras girl?

This week I went to one of my regular SCs. In 9 months of going to this SC, I've never bought any services from Amber the ruthless skanky extras girl. She scares the shit out of me. She whispered and offered HJ through FS in VIP the first time I ever went to my regular SC before I ever said I word to her. The first time I talked to her, "What do you during the day?" "I drink and get high", "you smoke?" "weed all day handsome" and shows off her mary jane tats, no shame, no shame. I am subtly about fun like that, she isn't. She talks super fast. She needs to smoke more blunts than she already does before coming to work. At another visit, Amber refused to do a test LD, VIP with extras or nothing since she "Im not going to tease your cock, fuck me like a real man". She gives off street worker vibes, 180 from GFE. No thanks. Today my CF was hiding in the DR like always, so out of complete boredom and it was a low dancer weekday, and because I never ever have gotten a LD from Amber the shark, I decided to get one just an experiment. Its been a couple months since Amber refused to do the test LD. This time Amber agrees. LD was way above the basic LD at this SC. A hand on my dick the whole time shielded from the camera. At this point, I notice my CF goes into the semi public LD room with another customer while Amber is grinding on me. Remember this fact for later. Before the LD started, I already decided Amber gets jizzed on her tits, so no titty sucking for me. Amber tried to make me suck her tits even though I didn't want to. Once I tasted them, I was correct in not wanting to titty suck, there was a bitter chemical taste on them. Either soap, hand sanitizer, or deodorant. Her stripper clothes also had a moldy laundry smell (did she pass out at the laundromat or find a customer and goto his car?). Overall a miserable experience. If I was an attention whore, I'd say I was raped by Amber. To stop the titty sucking I didn't want I started a conversation with Amber and talked with her for the rest of the LD while she grinded. I very politely confronted her that she was an extras girl. She told me why. "This is my club. The other dancers don't treat customers good. They never talk to them. They hide in the back. Look at [my CF] over there, she just shorted him [an obese short 250 lb with a sports jersey and sports shorts] on that [LD] song. CF lies to customers, she says she is Persian but is Russian. I go to every customer, no matter what. Every customer must be greeted every time. If nobody says hi to them, they will get up and not come back. I work here everyday. I save this club from closing." That paragraph explains her reasoning for being an extras girl. I dont disagree with anything Amber said. Since Amber's 1 dance on me started before CF started her 1 dance, and Amber's 1 dance on me ended after CF's 1 dance. Also CF told me she is Russian, but she does look Middle Eastern or Greek. Amber finished by saying she wont be here next week because she is going to Florida but will be back the week after that. Spring break but shes no college student ;)
