I work in an shopping outlet and we have a no photograph policy but staff are told to use a common sense approach to it. If we see someone with a couple of cameras strapped around them taking pics of the shops then we have a polite word pointing out the policy and the signs but we dont ask them to delete or anything, just to stop.
If we see families/fathers/mothers/ friends just taking general snaps then nothing is said.
Re the above policy concerning the shops themselves, the reason is you`d be surprised how many rivals send people out to photograph the displays and buildings.
