I can see both points as I do thing it's a little sketch to be taking pics of people's strollers, wheelchairs, etc. But that's me. I know we've certainly asked individuals about a device (thinking of a
scooter cover we saw). When we saw the owner, we asked him about it. But I can certainly see that it is in public and if no one is around....
Agree that one shouldn't take pics of kids. I actually have a huge issue with the way WDW does pics at Enchanted Tales with Belle. I was really appalled that when I took my niece to this attraction (having only boys, never did this before) we had a bunch of kids on our photo pass from the experience. Knowing that she's on others is cringe.
I do not agree with your statement that if the dog is being held, don't take a pic. But if the dog is laying down on its leash, it's ok? First off, my dog, as
@lanejudy stated, a service dog is considered part of me. My dog also weights 65lbs so there is no way for me to hold her. When we are waiting in a queue, she is trained to lay down. This is not an open invitation for someone to take her picture. Why do people feel the need to have this picture? To me, it's creepy. This is why you will always lot of times see "NO PHOTOS" on patches to service dog vests. It's a thing and most people I know who have a service dog do not want the dog's photo taken. And if you feel the need to take a picture (not you personally, ASK!!! Otherwise just admire the dog.
