The key is communication and, if neccessary negotiation.

I feel like you are coming at this situation and seeing it through the lense of your negative experience and are blind to other possibilities. I have to believe that you can see the situation where someone doesn't want there picture taken and doesn't freak out. Now we seem to have established that they have no rights and that you can do what you please. Answer this: Is this how you want to go through life? Do you want to forego communication and interaction and rely only on what your legal rights are? (clearly I am exagerating here).

The thing to remember is that anyone can be an ass. The question is do you want to be one and how do you react when you meet one?
