you should've asked me I've always said to my clients you pay $150 for pretty, young Japanese not for the service.
I never recommend Momo if you are a guy who's looking for a girl who provides GFE. She's pretty but... service? well..
It's totally different category.. different from Erica's and Mona's, and Sue's $150.. (I personally want to charge more for those girls but I'm not a bossㅋㅋ)

but shame...
1. Receptionist should've let you know why she's $150. (name out receptionist, I'll kill her)
2. you should've asked money back once you felt something wrong (when she played phone while you're having shower)

but it's yeah partly my bad so please kill me first !ㅜㅜ
