How to avoid snatch thieves ... Kiasu style!

I overheard in a Chinese program over the radio. The radio deejay was suggesting ways to overcome snatch thieves in Kuala Lumpur. The DJ said these days some ladies may not even carry anymore expensive handbags. Instead they trade with a "Bee Hiang" or "Wo Lai Yeh" plastic bags for grilled pork. It took me a while to figure out why must specifically these bags?! Then I realized because these bags are "tak halal". So the chances of people to snatch your bag may be lowered.
