I'll admit this is a bit boring, but I value it for it's historical significance. 20 years ago, it was take the photo, definitely with a flash, and go on. Now its take the photo, maybe without flash becuase you know it'll look better without it, then come and show your subject what you shot.
On a related note, even as far as 5 years ago, I was shooting a job, and was photographing some kids at a playground. They kept coming up to me, "take my picture!" and posing like gangsta's. Anyway, after I took the photo, a 6 or 7 year old pulled down gently on my film camera in the hopes of seeing the image on the back of camera.
