Matter of the fact, some of FJ's are true. I reckon many expats or locals have their personal views of local HKers but some chose to keep it to themselves, some broadcast it publicly. As a local guy and cx'er, I believe the description of certain hk girls are true to an extent. Perceptions are shaped by experiences and encounters. shouldn't blame others for their views. Though i studied college overseas, i grew up in HK. I know what it's like.
It's a money crazy city and you need to do what you can to survive. Some of FJ's might be hyperbole but if it doesn't occur to you nor does it hit you, why get so worked up? Unless you are fearful that the girl next to you would turnout that way, if not just ignore it. Time will always tell the truth.
I think it's best to go back to this thread title and discuss why the service is going bad instead.
