This type of stuff and worse happens all over the world every day, every hour.
You're absolutely right - but not by me! Perhaps Algol you can rejoice in the fact that you haven't been here long enough to regard this as normal, or maybe you have, but have maintained the entirely normal, decent human reaction of being shocked or bewildered, or conflicted when you consider this subject. Its a sad fact of life that in Hong Kong, behavior which most people would regard as unconscionable becomes, 'normalised'. If people around you are doing it, it must be OK right? but how many of you out there who 'join in' have had a twinge of doubt. Having the Craic about it in the Wanch or on Prune is one thing; do you still feel like the big guy telling your mates back where you came from or your Family, or don't you share with them for some unknown reason. Will you be proud of yourself when you have a daughter?
"Oldest Profession" is just the Oldest Excuse. Give to Charity, Pay your Maid more, Get a life - you know who you are.
Not Religious, don't have a "Maid", and no I'm not "Just Sayin", I judge you.
