That's the reason why I don't take photos in some crowded place, I am afraid to get approached and asked like that. Even with no Ill intention, it's still kinda scary. Anyways, it's cool that some people give a go to you photographing them and didn't reacted violently. Your photos looks cool. It shows the life of the people in there. And I can only see a few people walking in there. I hope the sellers in there get a loy of costumers.
