Depends on why I'm taking the picture. For the most part, I'm pretty stiff-necked. If I want to take a picture, and they happen to be in the shot, they are going to have their picture taken.

If I am doing personal stuff, working on framing, light, facial expression (I do a lot of intimate portraiture; not erotic, but reveletory, and it takes practice) I'll probably quit, if they come up and say it makes them uncomfortable, but more as an issue of not taking away their enjoyment of place.
