Thanks for sharing your experience in settling an unhappy case with Renee. Sarah is the best in serving clients so I am not surprised that you had a good time with Sarah.
From my experience, if you approach the owner of a small business reasonably, most of the time, the issues will be solved favourably. I usually do it discreetly and that makes the owner comfortable to handle the case. One of my bosses taught me when I was young to criticize in private but praise openly; this helped me a lot in winning friends and favours.
As I get older, I also tend to understand the other party better. I see Renee makes $30 if we book for an hour and she has to provide a place/towels...recruit and manage girls. I have a lot of "respect" for the girls, too; they have to put effort into massaging, which is physically exhausting and hurts their bodies in some way (most girls have pain from their hands to back after working for a while in massaging) and then use their body to entertain us. In short, it is really hard to earn money.
Personally, I very much agree with your perspective.
On the surface, this case seems to clearly fault Shangri-la as they scheduled multiple clients for Eva at the same time. However, it could also be that this guy arrived a few minutes late, causing his original appointment to be cancelled, and Eva naturally moved on to entertain other guests. In that case, it's a different story.
Regardless, one thing I must admit is that in top-notch spas like Shangri-la, those star-level girls are always extraordinarily busy and in high demand. Tina, Sarah, Coco, Eva, Amber, Cindy, their time slots sell out like hot items in a BestBuy on Boxing Day. Even if you've made an appointment, it doesn't necessarily secure your slot, because some guys, upon seeing these pretty girls, might pretend they've booked already to snatch your spot. I've encountered such incidents before.
Fortunately, all girls at Shangri-la, after being trained by Renee, have mastered the power to turn the mundane into the magical. The best examples are Kiki and Selena, whose services and GFE are no less than those of famous names. Give a big thumbs up to Renee...
