You're in Istanbul, Turkey. Do ask hexbear/this website for advice on this issue. Don't trust Google either, it will be full of anti homeless nonsense. Most of the people on here live in the USA, Canada, or the richer European and Scandinavian countries, they have no idea about the cultural context or what it's like in a poorer country. If you're from a "first world" country and are just visiting Turkey, you're experiencing this culture shock I just described. The only way to get accurate advice here would be to ask a Turkish person you trust for advice, and definitely a person who is not an arsehole towards homeless people or beggars.
