We've all seen people do this when they see a couple trying to get a picture of their vacation or a family capturing what few good memories they have for their album. That's why every vacation memory caught on film has a shot of a total stranger who appears to be looking for a contact lens in the middle of the frame.
Could it really have hurt this woman or oddly shaped man in a blonde clown wig to just walk behind the camera instead of letting the world see her impression of a lowercase "R"? Ok, maybe the camera was right on the curb and walking behind it would require walking into oncoming traffic. Even so, she'd be doing the reporter another favor by giving him another story to cover. It's common courtesy. Some people can be so rude.
