This man asked me whether I wanted him to smoke or not. I told him to light up. Not only because I think it occasionally looks good in pictures BUT because he was literally about to light his cigarette when I asked him for his picture. One thing about street shooting is that you(as the street shooter) don't want to be a nuisance to the person you're asking a picture from. You want to quickly take their picture without any bother and quickly leave so that there is no room for them to back out or have doubts about you.
