I hardly ever encounter beggars on the streets. But in some countries, you can find them begging at the markets and shopping malls. Once, when visiting a neighboring country, my hosts told me that for my own sake I had to ignore the beggars. If I showed the slightest interest in one, he would pursue and pester me until I gave him some money. And the moment I gave to one I would be very quickly swarmed by many others.
