Marcus Chin can surely attest to this.
If I remembered correctly, Marcus Chin had an affair with his assistant and they produced a child. He could not pay the maintenance fee that was awarded to his ex-wife and they went to court. Quan Yifeng's marriage failed partly because she had to financially support her family and her ex-husband. Not sure whether both men involved were Singaporean. There is no need to generalise people by nationalities.
From record, it seemed that this Quan Yifeng had a bad temper. However, I understood from one of my female colleagues that some old taxi uncles liked to pick on pretty female passengers and talked nonsense. I did not know the actual details of the case, we could not assume the taxi uncle was completely innocent.
For cases involving foreigners, the most talked about ones usually involved Westerners rather than Asians. Like the recent case involving the New Zealander who jumped bail that was picked up by SDP as well.
