Out-dated business model.
Let's face it, short term rooms suck. Nowadays, I see this as the option for newbs, once-a-year guys, and old guys stuck in the 90's. Honestly, one of my concerns with CC is that girls choose to work at this club solely because the short term room is the only option, thus giving them more control and power to manipulate.
Having your own room definitely shifts the balance of power in your favor. It's almost like the difference between inviting her back to your place vs her place. At your place, you are in control–not the girl or the towel boy.
And negotiating some arrangement OTC is just to complicated and too much work on any given night. I would only do this after I have seen the girl a couple times anyway.
