I went there once ages ago, and it was the most horrible hairstyle I've ever had in my life! (the worst thing is I had to go back to HK to get Adult ID a month later)
to be honest
they are not the most polite ppl in the world
but how creditable are you calling them 八婆 in the public ?
i am not saying what they do is right
maybe they are busy ?
i agree that their attitude according to your description is not so polite. but then, I thought that is usual because I've experienced those kinda attitudes at several places already...and I was like you too..
but honestly, do you think u were asking too many questions..like "ask front ask back"? because I like to try different hair salons, and when I first step into a salon, I always ask "hi, may I ask how much is _____"? and then the person there would always answer me in an impatient way making me look like I asked a cheap question, or they would just say..it's not expensive.
I thought any salon does not want to tell you the price before hand...and thy get pissed when you directly ask them how much their prices are (unless they have a list). but then, to those salons out there....getting a haircut is like eating a meal, we need to know how much it costs before we order!!
