In places where pictures are developped (at least locally) there is a strict privacy policy. Developers can't discuss what the pictures contain to anyone. If your husband develops pictures of him kissing his mistress, the developers can't show them to you no matter how much you beg and plead. With such a policy in place, most developers don't even bother really looking at the pictures aside from the necessary glances.
So why, Developer, did you look at mine? I went to pick up my pictures from your work station and before I even get the chance to see them myself (let alone offer to let you see them) you start flicking through them right in front of me! I have no control over whether or not you look at them before I pick them up, but to do so right in front of me? Really? He just stood there behind the counter, going through my pictures.
Holy unprofessional.
