A common sight in this part of the world:
Old, fat and/or ugly White man + young, attractive, thin Asian woman
When I say common, there are days I come across seven of these couples before lunchtime! Usually it doesn't bother me - especially when the couple seems to be equally matched in at least one area - age, attractiveness, etc. What does make my skin crawl is when I spot a 70-year old man with an Asian woman in her 20s. Gag.
I know what drives the women - money and security. So many of these women are dirt poor and doing anything they can to feed themselves and their families back home. (I'm writing this in earnest - no sarcasm here.) I get doing anything you can aside from prostitution to better your situation.
I can't figure out what drives the Rice King. Has he always had a thing for Asian women and so making his way to Hong Kong was a logical decision? Did he not really have a thing for Asian women until moving to Asia and then he realized he was missing out? Or is he just old, fat and ugly and can't find anyone else who wants to be with him?
It doesn't matter really. As long as we're all of consenting age, who am I to judge? But it does keep your gag reflex active.
Foot Note: Let me just be clear about something - not all white man + Asian woman couples fall into this category. You know a Rice King situation when you see one.
