Basically, we buy from them we take the risk out of
compassion.
But lets logicalize; if you are doing something "illegal" (that is
illegal in the eyes of our money-greedy gov) buy hawking food
without license, would you dare to give your customers food
poisoning??
I mean, when you approach the Satay Man for example, you will be
able to see whether he really means business or not. A genuinely
honest "illegal hawker" will look very clean and reasonably setup.
But you will see different standards from those YOUNGER punks who
are probably jobless foreigners from Batam., their bicycles or
motorbike will look really dirty, and so does the Satay
grill...
In this regard, we can see for ourselves.
