The first time it happens, I let it slide. Because as a previous poster said sometimes it's just a boo boo. But when it repeatedly happens..... well, I probably still won't say anything because I'm too chicken to speak up. But I will certainly be steaming in my seat!:fork: Usually I just repeat the phrase "Disney World is a happy place" over and over again in my head and try to calm down.:hammer:
I know it can take away from the experience (especially in say, the Mansion) but I've been there and seen it so many times, that I try not to let it bother me. Getting angry about it will only cause ME any pain, because likely the other person when confronted will either shrug it off and ignore you, or say something ignorant/colorful which will only further diminish the Disney magic.
Now, when I see people using flash photography in a museum, WATCH OUT. This art historian does not deal with people doing this as it can, over time, damage the paint, etc. But if you've ever been to the Louvre in front of the Mona Lisa, even with the glass case enclosing it, you know what a joke the "No Flash Photography" signs are...:ROFLOL:
