RE: If you own a pet store, would you let visitors take photos of your pets?
It would really depend on the situation. I have to mention first, like some members before me, that I would never have a pet shop that sells animals. One reason is, of course, I could never keep a shop full of animals in cages, and the other one is, well, I would have a problem giving them away. I would always doubt that the animals are getting proper care.
That aside, since this is a hypothetical question, I would allow taking pictures, without the flash. And as long as the animals don't mind. I probably wouldn't let people touch them though, especially not children. In my town, there is a pet shop near an elementary school, and when it first opened, children would pour in the tiny pet shop just to see the animals. I would not allow this, since the noise was surely bothering the animals, even if that would make me seem rude and might be bad for the business.
