I go to I&u the most and make replies here because it’s my favourite spa because I have breakfast beside them everyday and I repeat the same girls, they are on my rotation for almost 2 years. There’s always good and bad for different spa, but in my opinion I&u is like well-run you are correct.
Let’s look at a bigger picture if I go to any spa:
if the girl asked me for more than she should, I would just say no, or I would just accept if I really like her look and be like an one time thing, because I know she won’t last long and I probably won’t see her again
In terms of what you say about the grey hair girl, I’m sure jessica will investigate and act on it since she already replied to you as well.
