No one is passing any judgement here. Read it again. It's just good luck with little poke
If you have really worked in outsourcing industries like BPO you might be aware of customer response. It goes all the way from your nationality to accent to your education to country. You can't imagin what the guy will ask you for no reason.
The local outsourcing business that you mention is already in China and HK. But if China has to become no1 here it has to capture EU and USA market.
And that was the poke for. No teasing. Trust me you will talk to any customer but never to one from USA
I kicked that job in one month
