Would you "rescue" a pet from the pet store?

I don't know if I would be propelled to buy the fish or any other pet I see being mistreated in a pet shop to be honest. I might ask to see the store manager and inform them of the mistreatment. I would hope that would be enough to ensure that the fish would be better cared for. I don't think I would buy a pet that I really have never had and know nothing about caring for because I see it mistreated, but I guess some may feel that way, and there is really nothing wrong with that.
