So, if they charged less and for the same level of quality, they'd have more customers? lolduh
The ladies don't want to be working all day. Their whole selling point is good service. They want the long term client who visits monthly and spluges on the extra services. If you wanted a rando warm hole to bust in, head over to AA or a c-org. Each org has their own niche in the market and Gia and Jelly are the anchors ensuring all the ladies are trained up in having great service.
There is a reason they have the most travelers, it's a comfortable place to work (Ai was able to take every weekend off). Mongers like them because they quickly boot out the bad service providers and never rush. It's funny you complain about upcharges, because they didn't even offer those services at all before, lol.
