I know that when I worked retail, the managers (and our employee handbook) stated that we were not allowed to let customers take pictures in the storeI believe a lot of stores operate this way.
That's good info to know, it probably did not help that I was wearing a competitor's shirt when I was in there!
haha, that's the exact reason that we were told to not allow cameras in the store. something about competitors possibly stealing display ideas or something. it's all a bit ridiculous... but what can you do?
