Caleb, like I said it is loads of cash ... and agree with redwriter and yourself about being ripped off ...
Your gf can go back ask for an itemized receipt if she/you really want.
The prices should be posted as well. Also, did the most senior stylist do her hair as this also adds to the price - if she was not given the option between senior & junior stylist then she may have been seen by a junior and charged the price for a senior.
My understanding is that several women use and favor The Firm's services bc there is no / limited language obstacles.
Overall, the idea of customer service within salons in HK does not exist. It has taken me several horrible experiences with hair styles&color, the feeling of disgusted from being ripped off and cheated till I was able to find someone at a salon that styled my hair in a way that I like with honest service and price.
Personally, I would never pay that amount of money for my hair to be styled and colored but other women are content to pay that amount because there is little to no hassles associated with it.
