Can't Fault Roxana Really.
Roxana is a smart girl, who obviously knows how to read customers well. Roxana probably sensed Jnpr30 was smitten, and knew exactly how much she could get away with. She simply made a calculated business decision. In some cases, it is smarter for the girls to forget about building the customer relationship and just "go for the short money". Because the short money is guaranteed and paid upfront. The potential repeat business may never come, because most customer sentiment changes over time.
She knows Jnpr30 only attends a few times a year. So maybe she figures she gets about 1000 EUR from him in a given year. Statistically speaking she knows that many customers get bored and move onto new girls or they retire from the hobby, so she figured she might as well cash out and score 400-500 EUR from him in one night. Or maybe she knows she will quit the business soon, which means she might not be working the next time Jnpr30 attends. Or maybe she's been burned too many times. She used to give all of herself to every customer thinking that they would be loyal customers for life. But then found out that customers like Syzygies who repeat week after week are 1 in 10000.
Also when one girl sees another girl with a less customer-centric approach make just as much money as she does, that kills morale. I once had a job where I found out that the idiot sitting next to me was making as much as I was. At that point, I was like screw this! I lost all motivation to put in the extra hours, and immediately started looking for my next job.
What I am saying is the days of "Alles for funfzig" in Hessen is over. Girls, understandably, want to get paid the market rate. And the big Hessen FKKs, with its tourist-heavy customer base, drives that market rate up.
